By default we hide address math for many loads/stores in the x86 asm output
checks, which prevents us from seeing sometimes critical changes (offset
changes, stack positions etc.).

It's probably a large diff but always exposing this is probably a good idea.

We can probably reduce this at least a little by merging 32-bit/64-bit stack
variants (esp/rsp etc.) in regex patterns.

And some addresses we don't care about (constant pool loads?) so we should
still try to hide those.
