[Sparc] Fix incorrect MI insertion position for spilling f128.
Summary:
Obviously, new built MI (sethi+add or sethi+xor+add) for constructing large offset
should be inserted before new created MI for storing even register into memory.
So the insertion position should be *StMI instead of II.
before fixed:
std %f0, [%g1+80]
sethi 4, %g1 <<<
add %g1, %sp, %g1 <<< this two instructions should be put before "std %f0, [%g1+80]".
sethi 4, %g1
add %g1, %sp, %g1
std %f2, [%g1+88]
after fixed:
sethi 4, %g1
add %g1, %sp, %g1
std %f0, [%g1+80]
sethi 4, %g1
add %g1, %sp, %g1
std %f2, [%g1+88]
