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

Matt Arsenault 49dd4283ed R600/SI: Prefer selecting more e64 instruction forms.
Add some more tests to make sure better operand
choices are still made. Leave some cases that seem
to have no reason to ever be e64 alone.

Tom Stellard 1aaad6970c R600/SI: Add instruction shrinking pass
This pass converts 64-bit instructions to 32-bit when possible.

Matt Arsenault 72b31eee0b R600/SI: Change formatting of printed registers.
Print the range of registers used with a single letter prefix.
This better matches what the shader compiler produces and
is overall less obnoxious than concatenating all of the
subregister names together.

Instead of SGPR0, it will print s0. Instead of SGPR0_SGPR1,
it will print s[0:1] and so on.

There doesn't appear to be a straightforward way
to get the actual register info in the InstPrinter,
so this parses the generated name to print with the
new syntax.

The required test changes are pretty nasty, and register
matching regexes are now worse. Since there isn't a way to
add to a variable in FileCheck, some of the tests now don't
check the exact number of registers used, but I don't think that
will be a real problem.

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.

Tom Stellard 840214437b R600: Move CONST_ADDRESS folding into AMDGPUDAGToDAGISel::Select()
This increases the number of opportunites we have for folding.  With the
previous implementation we were unable to fold into any instructions
other than the first when multiple instructions were selected from a
single SDNode.
