[mips][ias] Expand on r238751 to cover as many relocs as possible.
Summary: Relocs that can be converted from absolute to PC-relative now do so if IsPCRel is true. Relocs that require PC-relative now call llvm_unreachable() if IsPCRel is false and similarly those that require absolute assert that IsPCRel is false. Note that while it looks like some relocs (e.g. R_MIPS_26) can be converted into the MIPS32r6/MIPS64r6 relocs (R_MIPS_PC*_S2), it isn't actually valid to do so. Placeholders have been left in the testcase for unsupported relocs and relocs that cannot be generated at the moment.
