3cd8cf6bbd R600/SI: Add FP mode bits to binary.
The default rounding mode to initialize the mode register needs
to be reported to the runtime. Fill in other bits a kernel
may be interested in setting for future use.

b52bf6a3b3 R600/SI: Prefer SALU instructions for bit shift operations
All shift operations will be selected as SALU instructions and then
if necessary lowered to VALU instructions in the SIFixSGPRCopies pass.

This allows us to do more operations on the SALU which will improve
performance and is also required for implementing private memory
using indirect addressing, since the private memory pointers must stay
in the scalar registers.

This patch includes some fixes from Matt Arsenault.

47fbbc2dc5 R600/SI: Implement SIInstrInfo::verifyInstruction() for VOP*
The function is used by the machine verifier and checks that VOP*
instructions have legal operands.

ebd4eec538 R600/SI: Fix broken encoding of DS_WRITE_B32
The logic in SIInsertWaits::getHwCounts() only really made sense for SMRD
instructions, and trying to shoehorn it into handling DS_WRITE_B32 caused
it to corrupt the encoding of that by clobbering the first operand with
the second one.

Undo that damage and only apply the SMRD logic to that.

Fixes some derivates related piglit regressions with radeonsi.

df4626ef15 R600/SI: Assign a register class to the $vaddr operand for MIMG instructions
The previous code declared the operand as unknown:$vaddr, which made
it possible for scalar registers to be used instead of vector registers.

9a256300f8 R600/SI: Emit config values in register value pairs.
Instead of emitting config values in a predefined order, the code
emitter will now emit a 32-bit register index followed by the 32-bit
config value.
