[Bug middle-end/34678] Optimization generates incorrect code with -frounding-math option (#pragma STDC FENV_ACCESS not implemented)

Would it make sense to have a function attribute to indicate that rounding mode
was changed as a side effect? This way, one could keep the default rounding
behavior and not incur a performance penalty, but at the same time
setroundingmode would work as expected.
