* x64: Remove incorrect `amode_add` lowering rules

This commit removes two incorrect rules as part of the x64 backend's
computation of addressing modes. These two rules folded a zero-extended
32-bit computation into the address mode operand, but this isn't correct
as the 32-bit computation should be truncated to 32-bits but when folded
into the address mode computation it happens with 64-bit operands,
meaning truncation doesn't happen.
