Drivers and state trackers that use LLVM for generating code, must
register the targets they use with LLVM's global TargetRegistry.
The TargetRegistry is not thread-safe, so all targets must be added
to the registry before it can be queried for target information.
When drivers and state trackers initialize their own targets, they need
a way to force gallivm to initialize its targets at the same time.
Otherwise, there can be a race condition in some multi-threaded
applications (e.g. glx-multihreaded-shader-compile in piglit),
when one thread creates a context for a driver that uses LLVM (e.g.
radeonsi) and another thread creates a gallivm context (glxContextCreate
does this).
The race happens when the driver thread initializes its LLVM targets and
then starts using the registry before the gallivm thread has a chance to
register its targets.
This patch allows users to force gallivm to register its targets by
calling the gallivm_init_llvm_targets() function.
v2:
- Use call_once and remove mutexes and static initializations.
- Replace gallivm_init_llvm_{begin,end}() with
gallivm_init_llvm_targets().

Unfortunately, we can't get rid of them entirely. The FS backend still
needs gl_program for handling TEXTURE_RECTANGLE. The GS vec4 backend still
needs gl_shader_program for handling transfom feedback. However, the VS
needs neither and we can substantially reduce the amount they are used.
One day we will be free from their tyranny.

As of now, uniform setup is more-or-less unified between vec4 and fs and no

Previously, we were counting up uniforms as we set them up. However, this

Previously, pack_uniform_registers worked based on the size of the uniform

Previously, we had a bunch of code in each stage to figure out how many
slots we needed in stage_prog_data.param. This code was mostly identical
across the stages and had been copied and pasted around. Unfortunately,
this meant that any time you did something special, you had to add code for
it to each of these places. In particular, none of the stages took
subroutines into account; they were working entirely by accident. By
taking this data from the NIR shader, we know the exact number of entries
