[PATCH] Fix PR68046 (part of PR61893)

This splits out the non-constant folding part of an earlier approved patch to make -ftrapv work better. The constant folding case is still broken (also ubsan doesn't handle it correctly). Bootstrapped and tested on x86_64-unknown-linux-gnu, applied to trunk. Richard. 2015-10-22 Richard

Move fold_trunc_transparent_mathfn to match.pd

This moves the fold rules for trunc, floor, ceil, round, nearbyint and rint in one go, since they're tested as a group. Most of the code is supporting the f(x)->x fold when x is known to be integer-valued. Like with the non-negative test, this is probably more elegantly handled by tracking range
