Handle constant fp classifications in fold-const-call.c
Move the constant "is finite", "is infinite" and "is nan" queries
to fold-const-call.c.
Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.
gcc/
* builtins.c (fold_builtin_classify): Move constant cases to...
* fold-const-call.c (fold_const_call_ss): ...here.
