intel/compiler/fs: Set up subgroup invocation as a system value

Subgroup invocation is computed using a vector immediate and some
dispatch-aware arithmetic.  Unfortunately, due to the vector arithmetic,
and the fact that it's frequently read 16-wide, it's not something that
can easily be CSEd by the back-end compiler.  There are a few different
possible approaches to this problem:

 1) Emit the code to calculate the subgroup invocation on-the-fly and
    trust NIR to do the CSE.  This is what we were doing.

 2) Add a back-end instruction for the subgroup ID.  This has the
    advantage of helping the back-end compiler with CSE but has the
    downside of very poor scheduling for the calculation because it has
    to be emitted in the back-end.

 3) Emit the calculation at the top of the program and re-use the
    result.  This gets rid of the CSE problem but comes at the cost of
    an extra live register.

This commit switches us from 1) to 3).  We choose to store the subgroup
invocation values as a W type to reduce the impact of the extra live
register.  Trusting NIR and using 1) was fine but we're soon going to
want to use the subgroup invocation value for other things in the
back-end compiler and this makes it much easier to do without having to

intel/fs: Use ANY/ALL32 predicates in SIMD32

We have ANY/ALL32 predicates and, for the most part, they work just
fine.  (See the next commit for more details.)  Also, due to the way
that flag registers are handled in hardware, instruction splitting is
able to split the CMP correctly.  Specifically, that hardware looks at
the execution group and knows to shift it's flag usage up correctly so a
2H instruction will write to f0.1 instead of f0.0.

Starting from GLSL ES 3.0, declarations with conflicting precision
qualifiers are explicitly prohibited. However GLSL ES 1.00 does not
clearly specify the behavior, except that

  "Uniforms are defined to behave as if they are using the same storage in
  the vertex and fragment processors and may be implemented this way.
  If uniforms are used in both the vertex and fragment shaders, developers
  should be warned if the precisions are different. Conversion of
  precision should never be implicit."

The word "used" is not clear in this context and might refer to
 1) declared (same as GLES 3.x)
 2) referred after post-processing, or
 3) linked after all optimizations are done.

Looking at existing applications, 2) or 3) seems to be widely adopted.
To avoid compatibility issues, turn the error into a warning if GLSL ES
version is lower than 3.0 and the data is dead in at least one of the
shaders.

drisw: Enable flush control for llvmpipe and softpipe

also improves, from about 2.25 to 3.09 fps (when it's that slow, you're
allowed to be that precise).

I'd have added it to swrast classic, but the testcase wants GL 3.0 and
shaders, and that's not a thing classic has, so I figured making it work

dri: Change __DriverApiRec::CreateContext to take a struct for attribs

Previously the CreateContext method of __DriverApiRec took a set of
arguments to describe the attribute values from the window system API's
CreateContextAttribs function. As more attributes get added this could
quickly get unworkable and every new attribute needs a modification for
every driver.

To fix that, pass the attribute values in a struct instead.  The struct
has a bitmask to specify which members are used. The first three members
(two for the GL version and one for the flags) are always set. If the
bit is not set in the attribute mask then it can be assumed the
attribute has the default value. Drivers will error if unknown bits in
the mask are set.

intel: Don't flush the old context in intelMakeCurrent

It shouldn't be necessary to flush the context within the driver
implementation because the old context is explicitly flushed in
_mesa_make_current which is called a little further on. It is useful to
only have a single place that flushes when switching contexts to make it
easier to later implement the GL_KHR_context_flush_control extension.

The flush in intelMakeCurrent was added in commit 5505865 to implement
the GLX semantics that the context should be flushed when it is
released.  When the commit was made there was no flush in
_mesa_make_current because it was only added later in 93102b4c. I think
that later commit effectively makes the first commit redundant.
