[Bug target/38350] New: odd extra unused stack space/register allocated with asm

["hp at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

For the attached code, there's no reason why the generated code at -O2 would
need an unused stack-slot (a second with -march=v10, a first with -march=v32)
when operand 5 (the last) of the asm is "g" than if it's "X".  Using "X" seems
a little awkward life-time-wise because the input is supposed to be valid.
I don't see this oddness on the host with native 4.1.2 on the host,
with/without -m32.
