x86: Always return pseudo register in ix86_gen_scratch_sse_rtx
ix86_gen_scratch_sse_rtx returns XMM7/XMM15/XMM31 as a scratch vector
register to prevent RTL optimizers from removing vector register. It
introduces a conflict with explicit XMM7/XMM15/XMM31 usage and when it
is called by RTL optimizers, it may introduce conflicting usages of
XMM7/XMM15/XMM31.
Change ix86_gen_scratch_sse_rtx to always return a pseudo register and
xfail x86 tests which are optimized with a hard scratch register.
