The semantics of __DRI2fenceExtensionRec::create_fence_fd are unclear on

both egl_dri2 and i965 believed they owned it. On eglDestroySync, that

travis: split the make target to three separate ones

The overall build time will be more, yet Travis runs multiple builds in
parallel so we're limited by the slowest one.

Things are split roughly as:
 - DRI loaders, classic DRI drivers, classic OSMesa, make check
 - All Gallium drivers (minus the SWR) alongside st/dri (mesa)
 - The Vulkan drivers - ANV and RADV, make check (anv)

v2:
 - rework RUN_CHECK to MAKE_CHECK_COMMAND
 - explicitly disable DRI loaders
 - generate linux/memfd.h locally and enable ANV
 - add libedit-dev

radeonsi: don't load unused compute shader input SGPRs and VGPRs

Basically, don't load GRID_SIZE or BLOCK_SIZE if they are unused, determine
whether to load BLOCK_ID for each component separately, and set the number
of THREAD_ID VGPRs to load. Now we should get the maximum CS launch wave
rate in most cases.

The use of PrimID in the pixel shader is too rare to deserve such
a sizable support code.

The initial idea of the VS epilog was to move the clipping code there and
remove it based on states, but optimized variants are now used to do that
and are easier to support, so the VS epilog has turned out to be not so
useful.
