Remove constant handling from fold_builtin_{,f}abs
fold_builtin_fabs and fold_builtin_abs had code to handle constant
arguments, but this simply duplicated what the following fold_build1_loc
would do for ABS_EXPR.
Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.
gcc/
* builtins.c (fold_builtin_fabs): Remove constant handling.
(fold_builtin_abs): Likewise.
