[mips] Add support for ELF64-mips and the R_MIPS_32/R_MIPS_64 relocs for it.
Summary:
This fixes several test failures when building LLVM on a MIPS host.
The failures were:
LLVM :: DebugInfo/enum.ll
LLVM :: DebugInfo/inlined-arguments.ll
LLVM :: DebugInfo/member-order.ll
LLVM :: DebugInfo/namespace.ll
LLVM :: DebugInfo/template-recursive-void.ll
LLVM :: DebugInfo/tu-composite.ll
LLVM :: DebugInfo/two-cus-from-same-file.ll
LLVM :: Linker/type-unique-simple-a.ll
LLVM :: Linker/type-unique-simple2.ll
