4905 - safe ptr lookup is now 6 instructions

The lines within '{}' can now be turned into a macro like `E_X = deref(E_X)`,
parameterizing the register being modified.

Assumes the input is in a register but also saved elsewhere, so it's safe
to clobber and replace with the result.

Compare commit 4894. Used to take 9 instructions, 8 of them making loads/stores.
Now it's 6 instructions, 4 of them loads/stores (the one non-local load
is unchanged, of course). Key is to not consume more registers so we don't
have to push/pop them.
