32-bit GOT calculation needs to do a call+pop to do get the EIP on
32-bit. LEA doesn't work because it there is no EIP relative ops like on
x86-64.
This causes a terrible block split on every GOT calculation without the
optimization in place.
Now the block can continue through this weird GOT calculation.
This will be worthwhile for our 32-bit thunks where for some reason the
GOT calculation can't be removed. The GOT is calculated even though it
isn't used.
