[X86] Fix incorrect/inefficient pushw encodings for x86-64 targets
...
Correctly support assembling "pushw $imm8" on x86-64 targets.
Also some cleanup of the PUSH instructions (PUSH64i16 and PUSHi16 actually
represent the same instruction)
This fixes PR23996

Implement some relaxations for arithmetic instructions. The limitation
...
on RIP relative relocations looks artificial, but this is a superset of
what we were able to do before.
