Stanislav Mekhanoshin c8127fc674 [AMDGPU] Fixed V_DIV_FIXUP_F16 selection on GFX9 
GFX9 should select opsel version.

Geoff Berry 1d53101387 [AMDGPU] isRenamable fixes to support copy forwarding 
Mark more opcodes as hasExtraSrcRegAllocReq so that their operands will
be marked as not renamable, to avoid copy forwarding violating the
constraint that only one operand may use the constant bus.

These changes fix a few mis-compiles when copy forwarding is enabled in
MachineCopyPropagation by D41835 (and were reviewed as part of that change).

Matt Arsenault 90c7593a75 AMDGPU: Remove global isGCN predicates 
These are problematic because they apply to everything,
and can easily clobber whatever more specific predicate
you are trying to add to a function.

Currently instructions use SubtargetPredicate/PredicateControl
to apply this to patterns applied to an instruction definition,
but not to free standing Pats. Add a wrapper around Pat
so the special PredicateControls requirements can be appended
to the final predicate list like how Mips does it.

Sam Kolton a2b9e2f755 [AMDGPU] CodeGen: check dst operand type to determine if omod is supported for VOP3 instructions 
Summary:
Previously, CodeGen checked first src operand type to determine if omod is supported by instruction. This isn't correct for some instructions: e.g. V_CMP_EQ_F32 has floating-point src operands but desn't support omod.
Changed .td files to check if dst operand instead of src operand.

Mark Searles e5c7832311 [AMDGPU] Force qsads instrs to use different dest register than source registers 
The V_MQSAD_PK_U16_U8, V_QSAD_PK_U16_U8, and V_MQSAD_U32_U8 take more than 1 pass in hardware. For these three instructions, the destination registers must be different than all sources, so that the first pass does not overwrite sources for the following passes.
