[AMDGPU] gfx11 Generate VOPD Instructions
We form VOPD instructions in the GCNCreateVOPD pass by combining
back-to-back component instructions. There are strict register
constraints for creating a legal VOPD, namely that the matching operands
(e.g. src0x and src0y, src1x and src1y) must be in different register
banks. We add a PostRA scheduler
mutation to put possible VOPD components back-to-back.
Depends on D128442, D128270

[AMDGPU] GFX11: automatically release VGPRs at the end of the shader
GFX11 has a new message type MSG_DEALLOC_VGPRS which can be used to
release a shader's VGPRs. Sending this at the end of a shader (just
before the s_endpgm) can help overall system performance in cases where
the s_endpgm would have to wait for outstanding VMEM stores to complete
before releasing the VGPRs.

Select SelectionDAG ops smul_lohi/umul_lohi to
v_mad_i64_i32/v_mad_u64_u32 respectively, with an addend of 0.
v_mul_lo, v_mul_hi and v_mad_i64/u64 are all quarter-rate instructions
so it is better to use one instruction than two.
Further improvements are possible to make better use of the addend
operand, but this is already a strict improvement over what we have
now.

[AMDGPU] Use new opcode for indexed vgpr reads
Introduce V_MOV_B32_indirect_read for indexed vgpr reads
(and rename the old V_MOV_B32_indirect to
V_MOV_B32_indirect_write) so they can be unambiguously
distinguished from regular V_MOV_B32_e32. Previously they
were distinguished by looking for extra implicit operands
but this is fragile because regular moves sometimes have
extra implicit operands too:
- either by accident, when instructions end up with
duplicate implicit operands (see e.g. D100939)
- or by design, when SIInstrInfo::copyPhysReg breaks a
multi-dword copy into individual subreg mov instructions
and adds implicit operands for the super-register.
The effect of this is that SIInstrInfo::isFoldableCopy can
be simplified and identifies more foldable copies. The test
diffs show that more immediate 0 values have been folded as
inline operands.
SIInstrInfo::isReallyTriviallyReMaterializable could
probably be simplified too but that is not part of this
patch.
