This patch extends fold_const_call so that it can handle internal
as well as built-in functions.
Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.
gcc/
* fold-const-call.h (fold_const_call): Replace built_in_function
arguments with combined_fn arguments.
* fold-const-call.c: Include case-cfn-macros.h.
(fold_const_call_ss, fold_const_call_cs, fold_const_call_sc)
(fold_const_call_cc, fold_const_call_sss, fold_const_call_ccc)
(fold_const_call_ssss, fold_const_call_1, fold_const_call): Replace
built_in_function arguments with combined_fn arguments.
* builtins.c (fold_builtin_sincos, fold_builtin_1, fold_builtin_2)
(fold_builtin_3): Update calls to fold_const_call.

The new routines operate on the built-in enum rather than on tree decls.
The idea is to extend this to handle internal functions too, with a
combined enum for both.
The patch also moves fold_fma too, with the same prototype. The long-term
plan is to replace FMA_EXPR with an internal function, for consistency
with the way that things like SQRT will be handled.
Tested on x86_64-linux-gnu, arm-linux-gnueabi and aarch64-linux-gnu.
gcc/
* builtins.h (fold_fma): Move to fold-const-call.h.
* builtins.c: Include fold-const-call.h.
(mathfn_built_in_2): New function, split out from...
(mathfn_built_in_1): ...here.
(do_real_to_int_conversion, fold_const_builtin_pow)
(fold_const_builtin_logb, fold_const_builtin_significand)
(fold_const_builtin_load_exponent, do_mpfr_arg1, do_mpfr_arg2)
(do_mpfr_arg3, do_mpfr_sincos, do_mpfr_bessel_n, do_mpc_arg1): Delete.
(fold_builtin_sincos): Use fold_const_call to handle constants.
(fold_builtin_1, fold_builtin_2, fold_builtin_3): Add explicit
checks for ERROR_MARK. Use fold_const_call to handle constant
folds for math functions.
(fold_fma): Move to fold-const-call.c.
* fold-const.c: Include fold-const-call.h.
* Makefile.in (OBJS): Add fold-const-call.o.
(PLUGIN_HEADERS): Add fold-const-call.h.
* realmpfr.h (real_from_mpfr): Allow the format to be specified
directly.
* realmpfr.c (real_from_mpfr): Likewise.
* fold-const-call.h, fold-const-call.c: New files.
