Marek Olsak 75170778ec R600/SI: Enable all tests that pass on VI without changes

Tom Stellard 49f8bfdcb7 R600/SI: Add a stub GCNTargetMachine
This is equivalent to the AMDGPUTargetMachine now, but it is the
starting point for separating R600 and GCN functionality into separate
targets.

It is recommened that users start using the gcn triple for GCN-based
GPUs, because using the r600 triple for these GPUs will be deprecated in
the future.

Tom Stellard 326d6ece94 R600/SI: Change all instruction assembly names to lowercase.
This matches the format produced by the AMD proprietary driver.

Tom Stellard 79243d9664 R600: Call EmitFunctionHeader() in the AsmPrinter to populate the ELF symbol table

Tom Stellard 50122a5890 R600: Match 24-bit arithmetic patterns in a Target DAGCombine
Moving these patterns from TableGen files to PerformDAGCombine()
should allow us to generate better code by eliminating unnecessary
shifts and extensions earlier.

This also fixes a bug where the MAD pattern was calling
SimplifyDemandedBits with a 24-bit mask on the first operand
even when the full pattern wasn't being matched.  This occasionally
resulted in some instructions being incorrectly deleted from the
program.

v2:
  - Fix bug with 64-bit mul

Tom Stellard 70f13dba15 R600/SI: Use -verify-machineinstrs for most tests
We can't enable the verifier for tests with SI_IF and SI_ELSE, because
these instructions are always followed by a COPY which copies their
result to the next basic block.  This violates the machine verifier's
rule that non-terminators can not folow terminators.
