[mips] Implement missing relocations in the integrated assembler.

Browse Source 
%got_hi, %got_lo, %call_hi, %call_lo, %higher, and %highest are now recognised
by MipsAsmParser::getVariantKind().

To prevent future issues with missing entries in this StringSwitch, I've added
an assertion to the default case.
