This marks the end of code sharing between r600 and radeonsi.
It's getting difficult to work on radeonsi without breaking r600.
A lot of functions had to be renamed to prevent linker conflicts.
There are also minor cleanups.

UE4Editor has this issue.
This commit prevents hangs (release build) or assertion failures (debug
build). It doesn't fix the editor, but catastrophic scenarios are
prevented.

Otherwise, code generation fails. This has become necessary since some
shaders are wrapped in control flow.

For inputs and outputs, indirect indexing is lowered by the GLSL compiler.
For temporaries, use alloca and disable the "promote-alloca" pass.
In the future, we could switch all codepaths to alloca permanently and
just rely on the "promote-alloca" pass.

This also fixes:
- GL45-CTS.arrays_of_arrays_gl.InteractionFunctionCalls2 (crash)

The code size decrease is positive, the register usage isn't. There is
a decrease in VGPR spilling for Tomb Raider, but increase in DiRT Showdown
and GRID Autosport.

LLVM 3.8:
- had broken indirect resource indexing
- didn't have scratch coalescing
- was the last user of problematic v16i8
- only supported OpenGL 4.1
This leaves us with LLVM 3.9 and LLVM 4.0 support for Mesa 17.2.

LLVM will lift inline assembly out of if-else-blocks if both paths have
the same inline assembly. Prevent this by adding an irrelevant unique
text to the assembly.
This requires the LLVM assembly parser to be initialized.
Furthermore, allow forcing subsequent computations to happen after the
optimization barrier by defining a data dependency.

For simplicitly, always store system values as 32-bit values or arrays

Initially this was a workaround for a bug introduced in LLVM 4.0
in the SimplifyCFG pass that caused image instrinsics to disappear
(because they were badly sunk). Finally, this is a win because it
decreases SGPR spilling and increases the number of waves a bit.
Although, shader-db results are good I think we might want to
remove it in the future once the issue is fixed. For now, enable
it for LLVM >= 4.0.
This also fixes a rendering issue with the speedometer in Dirt Rally.

Thanks to Dave Airlie for the patch.
