This regenerates these tests using utils/update_llc_test_checks.py so
that future changes in this area don't have the noise of lots of `@plt`
lines being added.
I also removed the `nounwind`s from the stack-realignment.ll test to
increase coverage on the generated call frame information.
Regenerated using:
./llvm/utils/update_llc_test_checks.py -u llvm/test/CodeGen/RISCV/*.ll
This has added comments to spill-related instructions and added @plt to
some symbols.

Most of the test changes are trivial instruction reorderings and differing
register allocations, without any obvious performance impact.

f32 values passed on the stack would previously cause an assertion in
unpackFromMemLoc.. This would only trigger in the presence of the F extension
making f32 a legal type. Otherwise the f32 would be legalized.
This patch fixes that by keeping LocVT=f32 when a float is passed on the
stack. It also adds test coverage for this case, and tests that also
demonstrate lw/sw/flw/fsw will be selected when most profitable. i.e. there is
no unnecessary i32<->f32 conversion in registers.
