Tim Renouf cfdfba996b [AMDGPU] Asm/disasm clamp modifier on vop3 int arithmetic 
Allow the clamp modifier on vop3 int arithmetic instructions in assembly
and disassembly.

This involved adding a clamp operand to the affected instructions in MIR
and MC, and thus having to fix up several places in codegen and MIR
tests.

Matthias Braun a83403892a MachineOperand/MIParser: Do not print debug-use flag, infer it 
The debug-use flag must be set exactly for uses on DBG_VALUEs.  This is
so obvious that it can be trivially inferred while parsing. This will
reduce noise when printing while omitting an information that has little
value to the user.

The parser will keep recognizing the flag for compatibility with old
`.mir` files.

Matt Arsenault 44a8a756e2 AMDGPU: Force shrinking of add/sub even if the carry is used 
The original motivating example uses a 64-bit add, so the carry
is used. Insert a copy from VCC. This may allow shrinking of
the used carry instruction. At worst, we are replacing a
mov to materialize the constant with a copy of vcc.

Matt Arsenault de6c421cc8 AMDGPU: Shrink insts to fold immediates 
This needs to be done in the SSA fold operands
pass to be effective, so there is a bit of overlap
with SIShrinkInstructions but I don't think this
is practically avoidable.
