Be more consistent in the naming convention for the various RET instructions to specify in terms of bitwidth.
Helps prevent future scheduler model mismatches like those that were only addressed in D44687.

In D68209, LiveDebugValues::transferDebugValue had a call to
OpenRanges.erase shifted, and by accident this led to a code path where
DBG_VALUEs of $noreg would not have their open range terminated, allowing
variable locations to extend past blocks where they were terminated.
This patch correctly terminates the open range, if present, when such a
DBG_VAUE is encountered, and adds a test for this behaviour.
