Move hypot folds to match.pd

Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.

gcc/
* builtins.c (fold_builtin_hypot): Delete.
(fold_builtin_2): Handle constant hypot arguments here.
* match.pd: Fold hypot(x, 0) and hypot(0, x) to x.  Canonicalize
hypot(x, x) to fabs(x)*sqrt(2).
