x86: widen @got{,pcrel} support to PUSH and APX IMUL
With us doing the transformation to an immediate operand for MOV and
various ALU insns, there's little reason to then not support the same
conversion for the other two insns which have respective immediate
operand forms. Unfortunately for IMUL (due to the 0F opcode prefix)
there's no suitable relocation, so the pre-APX forms cannot be marked
for relaxation in the assembler.
