Introduces a new concept for binding results to matchers
as per Chandler's request:
- introduces a new matcher base type BindableMatcher that
provides the bind() call
- makes all dynamic-cast matcher creation functions return
BindableMatchers; the special case about dynamic-cast
matchers is that the node they match on and the node
their child matchers match on are the same node, just
casted to a different type; thus, there is no ambiguity
on what bind() matches on; additionally, those are the
matchers that we name with nouns in the matcher language,
so it's easy for users to intuitively know which matchers
are bindable
To make this change possible, we got rid of a non-orthogonal
implementation of thisPointerType, which had an implicit
dynamic-cast matcher from CallExpr to CXXMemberCallExpr; as
alternative, we now provide a memberCall dynamic-cast matcher
and thisPointerType is a predicate on CXXMemberCallExpr.
Last, the ArgumentAdaptingMatcher is actually not required
for the implementation of makeDynCastAllOfComposite - this
simplification makes it more obvious where the bind() call
can be used based on the matcher creation function types.
