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.

and of course, makes code more consistent.

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.
DUAL_EXPORT can be enabled on r6xx/r7xx when all CBs use 16-bit export
and there is no depth/stencil export.

It seems DUAL_EXPORT on evergreen may be enabled when all CBs use 16-bit export
mode (EXPORT_4C_16BPC), also there should be at least one CB, and the PS
shouldn't export depth/stencil.

In some cases TGSI shader has more color outputs than the number of CBs,
so it seems we need to limit the number of color exports. This requires
different shader variants depending on the nr_cbufs, but on the other hand
we are doing less exports, which are very costly.

Shader variants are stored in the list, the key for lookup is based on the
states that require different hw shaders - currently it's rctx->two_side (all
gpus) and rctx->nr_cbufs (evergreen/cayman, when writes_all property is set).
v2:
- use simple list instead of keymap as suggested by Marek on irc
- call r600_adjust_gprs from r600_bind_vs_shader for r6xx/r7xx
(r600_shader_select isn't used for vertex shaders currently)
v3:
- fix call to r600_adjust_gprs - do it after updating current shader
Improves performance for some apps, e.g. FlightGear -

$CLANG_RESOURCE_DIR is the directory that contains all resources
needed by clang to compile programs. When clover uses clang to
compile kernels it needs to specify a resource dir, so that clang
can find its internal headers (e.g. stddef.h).
clang defines $CLANG_RESOURCE_DIR as $CLANG_LIBDIR/clang/$CLANG_VERSION
This patch adds the --with-clang-libdir option in order to accommodate
clang intalls to non-standard locations, and it also adds a check
to the configure script to verify that $CLANG_RESOURCE_DIR/include
contains the necessary header files.
