VisitFooTypeLoc() calls VisitFooType(); now, TraverseFooTypeLoc()
calls WalkUpFromFooType(). This allows clients that override
WalkUpFromFooType() to continue to work.  It also preserves the
property that Visit*() in the base visitor class is a no-op (s.t. a
subclass doesn't have to call Base::Visit*() when overriding
Visit*()).

Also fixes some typos in comments.
         
Also added a missing getDerived() inside
TraverseQualifiedTypeLoc(). The call is needed in case a subclass
overrides TraverseTypeLoc().

First loop test passed.  The data structure and search algorithm is still crude and in-flux.  But this milestone needed to be locked in.  Right now every loop is implemented in terms of a structure that will handle the most complicated {min, max} loop.  Though only *-loops are tested at the moment.  In a future iteration *-loops will likely be optimized a little more.  The only tests are for basic posix so far, but I have prototype code running for extended posix and ecma.  The prototype code lacks the complicating properties of the real <regex> requirements though.

interface needs implementations to be consistent, so any code which
wants to support different semantics must use a different interface.
It's not currently worthwhile to add a new interface for this new
concept.

Document that AliasAnalysis doesn't support cross-function queries.
