[PATCH] x86: allow to suppress default clobbers added to asm()s

While it always seemed wrong to me that there's no way to avoid the default "flags" and "fpsr" clobbers, the regression the fix for PR/60663 introduced (see PR/63637) makes it even more desirable to have such a mechanism: This way, at least asm()s with a single output and no explicit clobbers can a
