mesa: change GL_ALL_ATTRIB_BITS to 0xFFFFFFFF
This has been wrong for many years. It was originally 0x000FFFFF and long
ago there was discussion about whether GL_ALL_ATTRIB_BITS should include
the then-new GL_MULTISAMPLE_BIT bit. Eventually the ARB decided that
glPushAttrib(GL_ALL_ATTRIB_BITS) should save all current and future
attribute groups (hence ~0). Unfortunately, Mesa's gl.h was never updated.
This was just recently spotted by Eric Anholt and reported as a bug to the
ARB. Ian, Jon Leech and I discussed it at the ARB meeting and decided to
change Mesa's value to reflect the ARB's decision.

gallivm: fix opcode and function nesting
gallivm soa code supported only a single level of nesting for

mesa: Rename ElementArrayBufferObj to IndexBufferObj.
DirectX and most hardware documentation use the term "Index Buffer" to
refer to a buffer containing indexes into arrays of vertex data, which
allows random access to vertex data, rather than sequential access.
OpenGL uses a different term for this concept: "Element Array Buffer".
However, "Index Buffer" has become much more widespread. A quick
Google search shows 29,300 hits for "Element Array Buffer" vs.
82,300 hits for "Index Buffer."
Arguably, "Index Buffer" is clearer: an "element of an array" (or list)
usually refers to an actual item stored in the array, not the index used
to refer to it.
The terminology is also already used in Mesa: some VBO module code for
dealing with ElementArrayBufferObj names local variables "ib".

i965: Disable 3DSTATE_WM_HZ_OP fields.
Eric believes this to be wrong and unnecessary, as the command is
supposed to emit an implicit rectangle primitive. However, empirically
the pixel pipeline is completely unreliable without it. So for now, it
stays until someone comes up with a better solution.
We'll need to do better than this when we implement multisampling, HiZ,
or fast clears...but for now, this will do.

i965: Update multisampling state for Broadwell.
On previous platforms, 3DSTATE_MULTISAMPLE contained the number of
samples, pixel location, and the positions of each sample within a pixel
for each multisampling mode (4x and 8x). It was also a non-pipelined
command, presumably since changing the sample positions is fairly
drastic.
Broadwell improves upon this by splitting the sample positions out into
a separate non-pipelined state packet, 3DSTATE_SAMPLE_PATTERN. With
that removed, 3DSTATE_MULTISAMPLE becomes a pipelined state packet.
Broadwell also supports 2x and 16x multisampling, in addition to the 4x
and 8x supported by Gen7. This patch, however, does not implement 2x
and 16x.

glcpp: Don't enter lexer's NEWLINE_CATCHUP start state for single-line comments
In commit
6005e9cb28 a new start state of NEWLINE_CATCHUP was added to the
lexer. This start state is used whenever the lexer is emitting a NEWLINE token
to emit additional NEWLINE tokens for any newline characters that were skipped
by an immediately preceding multi-line comment.
However, that commit erroneously entered the NEWLINE_CATCHUP state for
single-line comments. This is not desired since in the case of a single-line
comment, the lexer is not emitting any NEWLINE token. The result is that the
lexer will remain in the NEWLINE_CATCHUP state and proceed to fail to emit a
NEWLINE token for the subsequent newline character, (since the case to match \n expects only the INITIAL start state).
The fix is quite simple, remove the "BEGIN NEWLINE_CATCHUP" code from the
single-line comment case, (preserving it only in exactly the cases where the
lexer is actually emitting a NEWLINE token).
Many thanks to Petri Latvala for reporting this bug and for providing the
minimal test case to exercise it. The bug showed up only with a multi-line
comment which was followed immediately by a single-line comment (without any
intervening newline), such as:
/*
*/ // Kablam!
Since
6005e9cb28, and before this commit, that very innocent-looking
combination of comments would yield a parse failure in the compiler.
