Android: drop static linking of R600 LLVM libraries

Inspired by Chih-Wei Huang and Zhen Wu similar patches

Linking against llvm with both static and shared may be avoided,
provided that libLLVM shared library for device supports
whole static R600/AMDGPU libraries, necessary for radeonsi/amdgpu.

Complementary changes, limited to android external/llvm project

Tested with marshmallow-x86 and nougat-x86 builds

mesa: remove _CurrentFragmentProgram from gl_pipeline_object

This was added in b527dd65c830a as a work around because fixed function
fragment shaders were tracked in ctx->FragmentProgram._Current as
a gl_program rather than gl_shader_program.

However after my refactoring of the program and shader structs
at the end of 2016 which culminated in c505d6d85222, we no longer
need gl_shader_program to track the current program making
_CurrentFragmentProgram obsolete.

i965: Make INTEL_DEBUG=bat decode VS/CLIP/GS/SF/WM/CC_STATE on Gen4-5.

This is something the original decoder did, but I didn't bother with
until now.  I recently had to debug an Ironlake issue, and wanted to
inspect VS_STATE.  So, now it's back.

The other packets in the switch statement are all Gen6/7+, where we
use offsets from dynamic state base address, so we don't need the
gtt_offset subtraction introduced here.  We might want to make a
helper for this hack at some point - perhaps when we introduce the
next occurance.

i965: Switch BRW_NEW_CURBE_OFFSETS to BRW_NEW_PUSH_CONSTANT_ALLOCATION.

The BRW_NEW_CURBE_OFFSETS dirty bit is signalled when changing the
partitioning of the Constant Buffer URB section between the various
shader stages, on Gen4-5.

BRW_NEW_PUSH_CONSTANT_ALLOCATION is basically the same thing on Gen7+.

So, save a bit, and use the new name.

i965: Only #if...#endif a single function or related section at a time.

Previously we guarded large swathes of code with #if GEN ... #endif
blocks.  This made it difficult to see which generations include what.

This patch splits up the #if..#endif sections so they surround a small
section of code - usually a single function/atom, or sometimes a group
of related functions.  It should make the code easier to work on.

i965: Drop INTEL_DEBUG=stats.

For whatever reason, we had an INTEL_DEBUG=stats option that enabled
various statistics counters on Gen4-5 systems.  It's been around
forever, though I can't think of a single time that it's been useful.

On Gen6+, we enable statistics all the time because they're necessary
to support various query object targets.  Turning them off would break
those queries.

Gen4-5 don't support those queries, so the statistics counters generally
aren't useful; we disabled them by default.  This patch disables them
altogether.

i965: Disable ARB_pipeline_statistics_query on Gen4-5.

We apparently enabled this on all platforms in Mesa 10.6.  However, it
was only ever implemented for Gen6+.  The Gen4-5 query code goes up in
flames with an "Unrecognized query target" unreachable() error if you
even attempt to use any of the new functionality.

This wasn't caught because the Piglit tests require OpenGL 3.0, which
Gen4-5 cannot support.  The extension spec does say 3.0 is required,
though I'm not sure why - it seems like 2.1 would work fine.

We could implement it anyway, but it's a little bit of a pain due to the
lack of hardware contexts (so we have to snapshot around batches).

Given that it's been 100% broken for two years and I haven't seen a bug
report about it, I'm not terribly inclined to care.  So, let it go.
