gallivm: Disable gallivm to fix build with LLVM 3.6

LLVM commit r218316 removes the JITMemoryManager class, which is
the parent for a seemingly important class in gallivm.  In order to
fix the build, I've wrapped most of lp_bld_misc.cpp in
if HAVE_LLVM < 0x0306 and modifyed the
lp_build_create_jit_compiler_for_module() function to return false
for 3.6 and newer which effectively disables the gallivm functionality.

I realize this is overkill, but I could not come up with a simple
solution to fix the build.  Also, since 3.6 will be the first release
without the old JIT, it would be really great if we could
move gallivm to use the C API only for accessing MCJIT.  There
is still time before the 3.6 release to extend the C API in
case it is missing some functionality that is required by gallivm.

ilo: rework pipeline workarounds

Add current_pipe_control_dw1 and deferred_pipe_control_dw1 to track what have
been done since lsat 3DPRIMITIVE and what need to be done before next
3DPRIMITIVE.  Based on them, we can emit WAs more smartly.

ilo: remove handle_invalid_batch_bo()

It was used to set has_gen6_wa_pipe_control to false when the batch buffer
changed.  When called from emit_flush() and others, it also unset
ILO_3D_PIPELINE_INVALIDATE_BATCH_BO so that the following emit_draw() will not
set has_gen6_wa_pipe_control to false again.  It sounded error-prone and was
just ugly.

We should be able to achieve the same goal by reset has_gen6_wa_pipe_control
in ilo_3d_pipeline_invalidate().  With handle_invalid_batch_bo() gone, the
emit functions can also be inlined.

PIPE_QUERY_PRIMITIVES_EMITTED is gone.

freedreno/ir3: fix TXB/TXL to actually pull the bias/lod argument

Previously we would get a potentially computed post-swizzle coord based
on the texture target info, which would not include the bias/lod in the
last argument.

The second argument does not have to be adjacent, so adjusting the order
array did not make sense.
