[AMDGPU] Assembler: Fix VOP3 only instructions
Separate methods to convert parsed instructions to MCInst:
- VOP3 only instructions (always create modifiers as operands in MCInst)
- VOP2 instrunctions with modifiers (create modifiers as operands
in MCInst when e64 encoding is forced or modifiers are parsed)
- VOP2 instructions without modifiers (do not create modifiers
as operands in MCInst)
- Add VOP3Only flag. Pass HasMods flag to VOP3Common.
- Simplify code that deals with modifiers (-1 is now same as
0). This is no longer needed.
- Add few tests (more will be added separately).
Update error message now correct.
