    d: Return promoted types in d_type_promotes_to when linkage is not D

    This enables warnings to be shown when a bad type is passed to va_arg
    inside an extern(C) or extern(C++) function.

    gcc/d/ChangeLog:

            PR d/97002
            * d-codegen.cc (d_build_call): Set input_location on CALL_EXPR.
            * d-lang.cc: Include function.h.
            (d_type_promotes_to): Do default conversions for C and C++
functions.
            * intrinsics.cc (expand_intrinsic_vaarg): Use build1_loc to build
            VA_ARG_EXPR.
