* config/tc-mips.c (append_insn): Use actual relocation size for new
fixp's. Don't relax overflow checking for partial_inplace relocations. Use the actual relocation type in combined relocs, not just the type of the first one. (macro_build_jalr): Use actual relocation size for new fix. (s_cpsetup, s_gpdword): Likewise.
