Resolving fixup_riscv_call by assembler when the linker relaxation diabled and the function and callsite within the same compile unit. And also adding static_assert after Infos array declaration to avoid missing any new fixup in MCFixupKindInfo in the future. Differential Revision: https://reviews.llvm.org/D47126 llvm-svn: 333487
