A few define_split's in the i386 backend modify RTL in place. This does
not work. This patch fixes all cases that do PUT_MODE on existing RTL.
Bootstrapped and tested; no regressions. Is this okay for trunk?
Hrm, this wants the testcase in that PR added I suppose. Will send
it separately.

* config/i386/i386.md (various splitters): Use copy_rtx before
doing PUT_MODE on operands.
Are the copies really needed? If we're slamming a mode into an
ix86_comparison_operator, we should be safe since those can't be shared.
Copying is just wasteful.
