The patch seems reasonable to me.
Renaming seems like a decent idea, since there is a use in jit.c, which
was added long after this was deprecated.
I count 22 mentions (including the declaration) of frame_register_read
in the tree right now. Getting rid of all of them doesn't seem so
difficult, aside from the testing. This would be clearly better...
At least one of the current uses seems suspicious since it ignores the
result. I assume I'm missing some context though.
