[PATCH] D10977: Allow {e, r}bp as the target of {read, write}_register.

[Reid Kleckner]

rnk added a subscriber: rnk.

Is it really that important to prevent people from hurting themselves by accessing ebp/rbp in a function without a frame pointer? I'd rather let them get hurt than suffer the extra code in LLVM.
