Sam Kolton 5196b88f07 [AMDGPU] Assembler: support SDWA for VOPC instructions 
Summary: dst_sel and dst_unused disabled for VOPC as they have no effect on result

Sam Kolton 945231ada5 [AMDGPU] AsmParser: Support for sext() modifier in SDWA. Some code cleaning in AMDGPUOperand. 
Summary:
sext() modifier is supported in SDWA instructions only for integer operands. Spec is unclear should integer operands support abs and neg modifiers with sext - for now they are not supported.
Renamed InputModsWithNoDefault to FloatInputMods. Added SextInputMods for operands that support sext() modifier.
Added AMDGPUOperand::Modifier struct to handle register and immediate modifiers.
Code cleaning in AMDGPUOperand class: organize method in groups (render-, predicate-methods...).

Sam Kolton 05ef1c940f [AMDGPU] Assembler: Custom converters for SDWA instructions. Support for _dpp and _sdwa suffixes in mnemonics. 
Summary:
Added custom converters for SDWA instruction to support optional operands and modifiers.
Support for _dpp and _sdwa suffixes that allows to force DPP or SDWA encoding for instructions.
