Chandler Carruth 0b73ccfe20 Rip out the floating point return type handling from the atomic builtin. It's
wrong, and we don't handle floating point value type arguments yet anyways.
Will add correct logic for both when I finish the patch.

Chandler Carruth 741e5cea77 Fix PR7600, and correctly convert the result of an atomic builtin to the
expected value type. This is necessary as the builtin is internally represented
as only operating on integral types.

Also, add a FIXME to add support for floating point value types.

Craig Silverstein 60f8b286ad Move traverseunqualifiedtypeloc over to the 'main' typeloc tree.
Note that this is a move -- we pretend that we were really looking
at the unqualified typeloc all along -- rather than a recursion, so
we don't follow the normal CRTP plan of going through
getDerived().TraverseTypeLoc.  If we did, we'd be traversing twice
for the same type (once as a QualifiedTypeLoc version of the type,
once as an UnqualifiedTypeLoc version of the type), which in effect
means we'd call VisitTypeLoc twice with the 'same' type.  This
solves that problem, at the cost of never seeing the qualified
version of the type (unless the client subclasses
TraverseQualifiedTypeLoc themselves).  It's not a perfect solution.
A perfect solution probably requires making QualifiedTypeLoc a
wrapper around TypeLoc -- like QualType is a wrapper around Type*
-- rather than being its own class in the type hierarchy.

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
