mesa: Add support for the GL_KHR_context_flush_control extension

The GL side of this extension just provides an accessor via glGetIntegerv for
the value of GL_CONTEXT_RELEASE_BEHAVIOR so it is trivial to implement. There
is a constant on the context for the value of the enum which is initialised to
GL_CONTEXT_RELEASE_BEHAVIOR_FLUSH. The extension is always enabled because it
doesn't need any driver interaction to retrieve the value.

If the value of the enum is anything but FLUSH then _mesa_make_current will
now refrain from calling _mesa_flush. This should only affect drivers that
explicitly change the enum to a non-default value.

i965/fs: Compute q-values for register allocation manually

Previously, we were allowing the register allocation code to do the
computation for us in ra_set_finalize.  However, the runtime for this
computation is O(c^4 * g) where c is the number of classes and g is the
number of GRF registers.  However, these q-values are directly computable
based on the way we lay out our register classes so there is no need for
the aweful runtime algorithm.

We were doing ok until commit 7210583eb where we bumped the number of
register classes from 11 to 16.  While startup times don't normally matter,
this caused piglit to take 4 times as long to run on Bay Trail.  This patch
should make generating the ra_set much faster and melt the piglit run
times.

v2: Fixed a couple of bugs.  I have now verified that the same q-values are
generated both ways.

The actual GRF mapping still needs to be doubled, but as far as the ra_set

Revert "freedreno/a3xx: only emit dirty consts"

This reverts commit 94bb33617d1e8978dc52b8aaa4eb41bfb6703f79.

freedreno: fix PIPE_TRANSFER_DISCARD_WHOLE_RESOURCE

fd_bo_cpu_prep() doesn't realize the bo is already referenced in
unflushed cmdstream.  It could be made to do so (but would have to be
implemented twice, ie. both for msm and kgsl).  But we still can't do
the expected thing if the caller isn't using _NOSYNC.  Because of the
way the tiling works, we need to build quite a bit of cmdstream at flush
time, which is not possible to do at the libdrm level.

So rather than trying to make fd_bo_cpu_prep() smarter than it can
possibly be, just *always* discard and reallocate if the
PIPE_TRANSFER_DISCARD_WHOLE_RESOURCE flag is set.

gallivm: Fix build with LLVM 3.3.

The setMCJITMemoryManager method doesn't exist in LLVM 3.3.

I thought I had tested the latest version of my earlier change with LLVM
3.3, but it looks I missed it.

Trivial.

gallivm: Properly update for removal of JITMemoryManager in LLVM 3.6.

JITMemoryManager was removed in LLVM 3.6, and replaced by its base class
RTDyldMemoryManager.

This change fixes our JIT memory managers specializations to derive from
RTDyldMemoryManager in LLVM 3.6 instead of JITMemoryManager.

This enables llvmpipe to run with LLVM 3.6.

However, lp_free_generated_code is basically a no-op because there are
not enough hook points in RTDyldMemoryManager to track and free the code
of a module.  In other words, with MCJIT, code once created, stays
forever allocated until process destruction.  This is not speicfic to
LLVM 3.6 -- it will happen whenever MCJIT is used regardless of version.

i965/vec4: Generate better code for ir_triop_csel.

Previously, we generated an extra CMP instruction:

   cmp.ge.f0(8)    g6<1>D          g1<0,4,1>F      0F
   cmp.nz.f0(8)    null            g6<4,4,1>D      0D

on that.  Rather than producing a boolean value and comparing it against
zero, we can just produce a condition code in the flag register.
