[RISCV] Do not grow the stack a second time when we need to realign the stack
This is a first change needed to fix a crash in which the emergency
spill splot ends being out of reach. This happens when we run the
register scavenger after we have eliminated the frame indexes. The fix
for the actual crash will come in a later change.
This change removes an extra stack size increase we do in
RISCVFrameLowering::determineFrameLayout.
We don't have to change the size of the stack here as
PEI::calculateFrameObjectOffsets is already doing this with the right
size accounting the extra alignment.
