Koakuma 23d209f350 [SPARC] Allow overaligned allocas (#107223) ...

SPARC ABI doesn't use stack realignment, so let LLVM know about it in
`SparcFrameLowering`. This has the side effect of making all overaligned
allocations go through `LowerDYNAMIC_STACKALLOC`, so implement the
missing logic there too for overaligned allocations.
This makes the SPARC backend not crash on overaligned `alloca`s and fix
