e1a4787d5d Work around bugs in MSVC "14" CTP 3's conversion logic 
It appears to ignore or find ambiguous MachineInstrBuilder's conversion
operators that allow conversion to MachineInstr* and
MachineBasicBlock::bundle_iterator.

As a workaround, add an explicit way to get the MachineInstr.

968e1f2f5b R600/SI: Add load / store machine optimizer pass. 
Currently this only functions to match simple cases
where ds_read2_* / ds_write2_* instructions can be used.

In the future it might match some of the other weird
load patterns, such as direct to LDS loads.

Currently enabled only with a subtarget feature to enable
easier testing.
