[AMDGPU] Add AV class spill pseudo instructions
While enabling vector superclasses with D109301,
the AV spills are converted into VGPR spills by
introducing appropriate copies. The whole thing
ended up adding two instructions per spill (a copy
+ vgpr spill pseudo) and caused an incorrect
liverange update during inline spiller.
This patch adds the pseudo instructions for all
AV spills from 32b to 1024b and handles them in
the way all other spills are lowered.

[AMDGPU] Enable copy between VGPR and AGPR classes during regalloc
Greedy register allocator prefers to move a constrained
live range into a larger allocatable class over spilling
them. This patch defines the necessary superclasses for
vector registers. For subtargets that support copy between
VGPRs and AGPRs, the vector register spills during regalloc
now become just copies.
