Follow the X86, Mips, and RISCV renaming. > "Relocation modifier" suggests adjustments happen during the linker's relocation step rather than the assembler's expression evaluation. > "Relocation specifier" is clear, aligns with Arm and IBM AIX's documentation, and fits the assembler's role seamlessly. In addition, rename *MCExpr::getKind, which confusingly shadows the base class getKind.
