Detailed Description

A sentinel class for ensuring that the "vect_location" global gets
reset at the end of a scope.

The "vect_location" global is used during dumping and contains a
location_t, which could contain references to a tree block via the
ad-hoc data.  This data is used for tracking inlining information,
but it's not a GC root; it's simply assumed that such locations never
get accessed if the blocks are optimized away.

Hence we need to ensure that such locations are purged at the end
of any operations using them (e.g. via this class).
