asm: Generalize memory operand syntax to a flat term list
...
Parse `[...]` as `term { (+|-) term }` where each term is `operand [ (*|<<|>>) operand ]`.
This allows for constant-only terms to be folded in-place, especially for things like displacement.
e.g. `[p + 8*32]` means `[p + 256]`.
Term order is also free: `[8 + p]` == `[p + 8]`
