[pushed] Darwin: Fix a type mismatch warning for a non-GCC bootstrap compiler.

[Iain Sandoe via Gcc-patches]

DECL_MD_FUNCTION_CODE() returns an int, on one particular compiler the
code in darwin_fold_builtin() triggers a warning.

Fixed thus.

tested on x86_64-darwin18, powerpc-darwin9, cross to powerpc-darwin8.
pushed to master, thanks

gcc/ChangeLog:

        * config/darwin.cc (darwin_fold_builtin): Make fcode an int to
        avoid a mismatch with DECL_MD_FUNCTION_CODE().
