RISC-V: Promote type correctly for libcalls
- argument and return value for libcall won't promote at
default_promote_function_mode_always_promote, however we expect it
should sign-extend as normal function.
- Witout this patch, this test case will fail at -march=rv64i -mabi=lp64.
- The implementation of riscv_promote_function_mode is borrowed from MIPS.
