Move the X86 PC-relative fixup adjustment from X86MCCodeEmitter::emitImmediate to MCAssembler, leveraging a generalized evaluateFixup. This saves a MCBinaryExpr. For `call foo`, the fixup expression is now `foo` instead of `foo-4`. There is no change in generated relocations. In bolt/lib/Target/X86/X86MCPlusBuilder.cpp, createRelocation needs to decrease the addend. Both max-rss and instructions:u show a minor decrease. https://llvm-compile-time-tracker.com/compare.php?from=ea600576a6f94d6f28925c4b99962cc26b463c29&to=016e8fd4ddf851e5555f606c6394241d68f1a7bb&stat=max-rss&linkStats=on Next: Update targets that use FKF_IsAlignedDownTo32Bits to define `evaluateFixup` and remove FKF_IsAlignedDownTo32Bits from the generic code.
