tgsi_ureg was recently enhanced to support local temporaries, and as result
temps are declared individually.
This change avoids many TEMP register declarations on common shaders.
(And fixes performance regression due to mismatches against performance
sensitive shaders.)

The templated copy constructor doesn't prevent the compiler from
emitting a default copy constructor, which leads to inconsistent
memory handling and was reported to cause segfaults when doing event
manipulation.

The function internalizer pass marks non-kernel functions as internal,
which enables optimizations like function inlining and global dead-code
elimination.
v2:
- Pass vector arguments by const reference
Removed u_half.py used to generate the table for previous method.
Previous implementation of float to half conversion was faulty for
denormalised and NaNs and would require extra logic to fix,
thus making the speedup of using tables irrelevant.

Some parameters need to be checked only once.
check_valid_to_render needs to be called only once.
The validate function is based on the one for DrawElements.

This is a cleanup for ARB_transform_feedback3, where
GL_MAX_TRANSFORM_FEEDBACK_BUFFERS is introduced for interleaved attribs and
has the same meaning as GL_MAX_.._SEPARATE_ATTRIBS for separate attribs.
Also, the maximum number of TFB buffers is reduced from 32 to 4, which makes
this patch useful even without the extension.
I don't know of any hardware which can do more than 4.

Doesn't really change the generated assembly, but produces more compact IR,
and of course, makes code more consistent.

For some reason regular gcc on Linux didn't catch these but the mingw
compiler did (generated errors, not warnings).
v2: include the changes in src/mapi/ too
Fixes the es2 build with gcc.
Note: in glext.h the prototypes for glShaderSource() and glShaderSourceARB()
disagree: only the former has the extra const qualifier.

Previously, we were counting gl_FrontFacing, gl_FragCoord and gl_PointCoord
against the limit of varying variables. This prevented some valid shaders
from linking.
The other potential solution to this is to have the driver advertise
more varying vars or set the GLSLSkipStrictMaxVaryingLimitCheck flag.
But the above-mentioned variables aren't conventional varying attributes
so it doesn't seem right to count them.

Since we don't have them in hw we emulate them in the shader. Although not
recommended by the spec it is legit.
As a side effect we also get GL 2.1. I think this is as far as we can take
the i915.
