[dev.ssa] cmd/compile: PPC64, FP to/from int conversions.dev.ssa
Passes ssa_test.
Requires a few new instructions and some scratchpad
memory to move data between G and F registers.
Also fixed comparisons to be correct in case of NaN.
Added missing instructions for run.bash.
Removed some FP registers that are apparently "reserved"
(but that are also apparently also unused except for a
gratuitous multiplication by two when y = x+x would work
just as well).
Currently failing stack splits.
Updates #16010.
