LFS/STFS load and store FP values, not integer ones. This change allows us
to codegen this: float foo() { return 1.245; }
into this:
_foo:
lis r2, ha16(.CPI_foo_0)
lfs f1, lo16(.CPI_foo_0)(r2)
blr
instead of this:
_foo:
lis r2, ha16(.CPI_foo_0)
lfs r2, lo16(.CPI_foo_0)(r2) <-- ouch
or f1, r2, r2 <-- ouch
blr
with the dag isel.
