u_primconvert: Copy min/max_index from the original primitive.
These values are supposed to be the minimum/maximum index values used to
read from the vertex buffers. This code either copies index values out of
the old IB (so, same min/max as the original draw call), or generates a
new IB (using index values between the start and the start + count of the
old array draw info, which just happens to be what min/max_index are set
to by st_draw.c).
We were incorrectly setting the max_index in the
converting-from-glDrawArrays case to the start vertex plus the number of
vertices generated in the new IB, which broke QUADS primitive conversion
on VC4 (where max_index really has to be correct, or the kernel might
reject your draw call due to buffer overflow).

draw: hack around weird primitive id input in gs
The distinction between system values and ordinary inputs is not very
obvious in gallium - further fueled by the fact that they use the same
semantic names.
Still, if there's any value which imho really is a system value, it's the
primitive id input into the gs (while earlier (tessleation) stages could read
it, it is _always_ generated by the system). For some odd reason though (which
I'd classify as a bug but seems too complicated to fix) the glsl compiler in
mesa treats this as an ordinary varying, and everything else after that
(including the state tracker and other drivers) just go along with that.
But input fetching in gs for llvm based draw was definitely limited to the
ordinary (2-dimensional) inputs so only worked with other state trackers,
the code was also additionally relying on tgsi_scan_shader filling
uses_primid correctly which did not happen neither (would set it only for
all stages if it was a system value, but only set it for the fragment shader
if it was an input value).

Looking at the history, it appears that this code has used BRW_EXECUTE_8

a separate SIMD16 backend that didn't. Presumably, when we added SIMD16

Fixing the bug required only removing code from glcpp. When first testing the
details of expansions involving commas, I had come to the mistaken conclusion
that an expanded comma should never be treated as an argument separator, (so
had introduced the rather ugly COMMA_FINAL token to represent this).
In fact, an expanded comma should be treated as a separator, (as tested here),
and this treatment can be avoided by judicious use of parentheses (as also
tested here).

glsl/glcpp: Integrate recent glcpp-test-cr-lf test into "make check"
Beyond just listing this in the TESTS variable in Makefile.am, only minor
changes were needed to make this work. The primary issue is that the build
system runs the test script from a different directory than the script
itself. So we have to use the $srcdir variable to find the test input files.
Using $srcdir in this way also ensures that this test works when using an
out-of-tree build.

glsl/glcpp: Fix glcpp-test to correctly extract test-specific arguments
The (optional) test-specific command-line arguments to be passed to glcpp are
embedded within the source files of some tests, and glcpp-test uses grep to
extract them.
Of course, grep is line-based and looks for the native line-separator to
determine line boundaries. So, for files using non-native line separators,
grep was getting quite confused and passing bogus arguments to glcpp.
Fix this by canonical-izing the line separators in the source file prior to
using grep.
With this commit, the glcpp-test-cr-lf tests pass entirely:
\r: 143/143 tests pass
\r\n: 143/143 tests pass

glsl/glcpp: Fix line-continuation code to handle multiple newline flavors
Sometimes the newline separator is a single character, and sometimes it is two
characters. Before we can fold away and line-continuation backslashes, we
identify the flavor of line separator that is in use.
With this identified, we then correctly search for backslashes followed
immediately by the first character of the line separator.
Also, when re-inserting newlines to replace collapsed newlines, we carefully
insert newlines of the same flavor.
With this commit, almost all remaining test are fixed as tested by

extract test-specific command-line options from the source files.)

glsl/glcpp: Treat CR+LF pair as a single newline
The GLSL specification says that either carriage-return, line-feed, or both
together can be used to terminate lines. Further, it says that when used
together, the pair of terminators shall be interpreted as a single line.
This final requirement has not been respected by glcpp up until now, (it has
been emitting two newlines for every CR+LF pair).
Here, we fix the lexer by using a regular expression for NEWLINE that eats
up both "\r\n" (or even "\n\r") if possible before also considering a single
'\n' or a single '\r' as a line terminator.
Before this commit, the test results are as follows:
\r: 135/143 tests pass

glsl/glcpp: Add test script for testing various line-termination characters
The GLSL specification has a very broad definition of what is a
newline. Namely, it can be the carriage-return character, '\r', the newline
character, '\n', or any combination of the two, (though in combination, the
two are treated as a single newline).
Here, we add a new test-runner, glcpp-test-cr-lf, that, for each possible
line-termination combination, runs through the existing test suite with all
source files modified to use those line-termination characters. Instead of
using the .expected files for this, this script assumes that the regular test
suite has been run already and expects the output to match the .out
files. This avoids getting 4 test failures for any one bug, and instead will
hopefully only report bugs actually related to the line-termination
characters.
The new testing is not yet integrated into "make check". For that, some
munging of the testdir option will be necessary, (to support "make check" with
out-of-tree builds). For now, the scripts can just be run directly by hand.

glsl/glcpp: Fix for macros that expand to include "defined" operators
Prior to this commit, the following snippet would trigger an error in glcpp:
#define FOO defined BAR
#if FOO
#endif
The problem was that support for the "defined" operator was implemented within
the grammar, (where the parser was parsing the tokens of the condition
itself). But what is required is to interpret the "defined" operator that
results after macro expansion is performed.
I could not find any fix for this case by modifying the grammar alone. The
difficulty is that outside of the grammar we already have a recursive function
that performs macro expansion (_glcpp_parser_expand_token_list) and that
function itself must be augmented to be made aware of the semantics of the
"defined" operator.
The reason we can't simply handle "defined" outside of the recursive expansion
function is that not only must we scan for any "defined" operators in the
original condition (before any macro expansion occurs); but at each level of
the recursive expansion, we must again scan the list of tokens resulting from
expansion and handle "defined" before entering the next level of recursion to
further expand macros.
And of course, all of this is context dependent. The evaluation of "defined"
operators must only happen when we are handling preprocessor conditionals,
(#if and #elif) and not when performing any other expansion, (such as in the
main body).
To implement this, we add a new "mode" parameter to all of the expansion
functions to specify whether resulting DEFINED tokens should be evaluated or
ignored.
One side benefit of this change is that an ugly wart in the grammar is
removed. We previously had "conditional_token" and "conditional_tokens"
productions that were basically copies of "pp_token" and "pp_tokens" but with
added productions for the various forms of DEFINED operators. With the new
code here, those ugly copy-and-paste productions are eliminated from the
grammar.
A new "make check" test is added to stress-test the code here.

glsl/glcpp: Add explicit error for "#define without macro name"
Previously, glcpp would emit an error like this if <EOF> happened to occur
immediately after the "#define", but in general would just get confused,
(leading to un-helpful error messages).
To fix things to generate a clean error message, we do a few things:
1. Don't require horizontal whitespace immediately after #define
2. Add a production for the error case, (DEFINE_TOKEN followed
immediately by a NEWLINE token).
3. Make the lexer reset to the <INITIAL> state after every NEWLINE.
This 3rd point prevents the lexer from getting so confused and generating
further spurious errors in the file because it was stuck in the <DEFINE> start
condition.
We also drop the similar error message from the <EOF> rule since the
newly-added rule will have already printed the error message.
