Ok.

Hi!
When working on clobber sinking, I've noticed that
optimize_clobbers would mistakenly remove just one clobber
instead of all consecutive ones, because gsi_remove moves
the iterator to the next rather than previous stmt (i.e.
GIMPLE_RESX if no debug stmts) and we return in the next iteration.
