This is only a half of the work. The next patch will handle
gl_SampleID/SamplePos, which is the other half of ARB_sample_shading.

We will only do depth-only or stencil-only decompress blits, whichever is
needed by textures, instead of always doing both.

As of version 15 of the EGL_KHR_create_context spec, debug contexts
are allowed for ES contexts. We should allow creation instead of
erroring.
While we're here provide a more comprehensive checking for the other two
flags - ROBUST_ACCESS_BIT_KHR and FORWARD_COMPATIBLE_BIT_KHR

Now that everything comes in through NIR, we can pick this directly out of
the shader source and don't need to reference the gl_fragment_program.

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.

It doesn't exist for anything other than an assert that, as far as I can
tell, isn't possible to trip. Soon, we will remove prog from the visitor
entirely and this will become even more impossible to hit.
