ISD::MUL and ISD:UMULO are the same except that UMULO sets an overflow
bit. Since we aren't using the overflow bit, we should use ISD::MUL.

In r217636, the value stored in KernelInfo.Num[VS]GPRSs was changed from
the highest GPR index used to the number of gprs in order to be
consistent with the name of the variable.
The code writing the config values still assumed that the value in this
variable was the highest GPR index used, which caused the compiler to
over report the number of GPRs being used.

shim between the TargetTransformInfo immutable pass and the Subtarget
via the TargetMachine and Function. Migrate a single call from
BasicTargetTransformInfo as an example and provide shims where TargetMachine
begins taking a Function to determine the subtarget.
No functional change.

Since read2 / write2 are emitted for 4-byte aligned 8-byte
accesses, these are seen by the scheduler.
The DAG scheduler is semi-deprecated, so just
ignore these for now.

Only 1 decimal place should be printed for inline immediates.
Other constants should be hex constants.
Does not include f64 tests because folding those inline
immediates currently does not work.

Instructions are now generally selected to the e64 forms originally,
and shrunk down later. Rename foldOperands to legalizeOperands,
since that's really most of what it tries to do.

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.

Refactored the R600_LDS_1A2D class a bit to get it to actually work.
It seemed to be previously unused and broken.
We also have to disable the conversion to the noret variant for now in
R600ISelLowering because the getLDSNoRetOp method only handles 1A1D LDS ops.
Someone can feel free to modify the AMDGPU::getLDSNoRetOp method to
work for more than 1A1D variants of LDS operations. It's being left as a
future TODO for now.

Need to convert the 64 element offset into bytes, not just the element
size like the normal case instructions.
Noticed by inspection. This can't be hit now because
st64 instructions aren't emitted during instruction selection,
and the post-RA scheduler isn't enabled.

Assert in scheduler from an inserted copy_to_regclass from
a constant.
This only seems to break sometimes when a constant initializer
address is forced into VGPRs in a non-entry block. No test
since the only case I've managed to hit only happens with a future
patch, and that case will also not be a problem once scalar instructions
are used in non-entry blocks.

We must constrain the destination register class of legalized operands
to a VGPR class or else the illegal operand may be folded back into
the instruction by the register coalescer.

There is no test case for this, because this failure depends on a
