glsl: Delete unused gl_uniform_driver_format enum values.

A while back, Matt made the uniform upload functions simply upload
ctx->Const.UniformBooleanTrue for boolean values instead of 0/1, which
removed the need to convert it later.  We also set UniformBooleanTrue to
1.0f for drivers which want to treat booleans as 0.0/1.0f.

Nothing ever sets these, so they are dead.

i965/fs: Generate better code for ir_triop_csel.

Previously, we generated an extra CMP instruction:

   cmp.ge.f0(8)   g4<1>D          g2<0,1,0>F      0F
   cmp.nz.f0(8)   null            g4<8,8,1>D      0D
   (+f0) sel(8)   g120<1>F        g2.4<0,1,0>F    g3<0,1,0>F

The first operand is always a boolean, and we want to predicate the SEL
on that.  Rather than producing a boolean value and comparing it against
zero, we can just produce a condition code in the flag register.

Now we generate:

   cmp.ge.f0(8)    null            g2<0,1,0>F      0F
   (+f0) sel(8)    g124<1>F        g2.4<0,1,0>F    g3<0,1,0>F

total instructions in shared programs: 5473459 -> 5473253 (-0.00%)
instructions in affected programs:     6219 -> 6013 (-3.31%)

i965/vec4: Simplify visit(ir_expression *)'s result_src/dst setup.

Using dst_reg(this, ir->type) automatically sets the writemask to the
proper size for the type; src_reg(dst_reg) preserves that.  This should
be equivalent, but less code.

Note that src_reg(dst_reg) either uses SWIZZLE_XXXX or SWIZZLE_XYZW, so
the old code did need the manual writemask adjustment, since it
constructed the registers the other way around.

If the user calls util_blitter_cache_all_shaders() set a flag and assert
that we never try to create any new fragment shaders after that point.
If the assertions fails, it means we missed generating some shader in

gallivm,llvmpipe,clover: Bump required LLVM version to 3.3.

We'll need to update gallivm for the interface changes in LLVM 3.6, and
the fewer the number of older LLVM versions we support the less hairy that
will be.

As consequence HAVE_AVX define can disappear.  (Note HAVE_AVX meant
whether LLVM version supports AVX or not.  Runtime support for AVX is
always checked and enforced independently.)

Verified llvmpipe builds and runs with with LLVM 3.3, 3.4, and 3.5.

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.
