* tree-ssa-sccvn.c (simplify_binary_expression): Avoid
folding if nothing changed.
(simplify_unary_expression): New function. Do tree combining
on conversion like codes.
(try_to_simplify): Call it.
* builtins.c (fold_builtin_cexp): Fold the built expressions.
* fold-const.c (fold_unary): Test result of get_callee_fndecl().
* g++.dg/tree-ssa/pr27090.C: Remove XFAILs.
