Set the source location for the "member reference base type ... is not a
structure or union" diag to point at the operator rather than the member name.
If we're giving this diagnostic because of a typo'd '.' in place of a ';' at
the end of a line, the caret previously pointed at the identifier on the
following line, which isn't as helpful as it could be. Pointing the caret at
the '.' makes it more obvious what the problem is.

This is needed to ensure that we always report issues in the correct
function. For example, leaks are identified when we call remove dead
bindings. In order to make sure we report a callee's leak in the callee,
we have to run the operation in the callee's context.

This change required quite a bit of infrastructure work since:
 - We used to only run remove dead bindings before a given statement;
here we need to run it after the last statement in the function. For
this, we added additional Program Point and special mode in the
SymbolReaper to remove all symbols in context lower than the current
one.
 - The call exit operation turned into a sequence of nodes, which are
now guarded by CallExitBegin and CallExitEnd nodes for clarity and
convenience.

(Sorry for the long diff.)

followed by an identifier as declaration specificer (except for ObjC).
This allows e.g. an out-of-line C++ member function definitions to be
recognized as functions and not as variable declarations if the type
name for the first parameter is not recognized as a type--say, when there
is a function name shadowing an enum type name and the parameter is
missing the "enum" keyword needed to distinguish the two.

Note that returning TPResult::Error() instead of TPResult::True()
appears to have the same end result, while TPResult::Ambiguous()
results in a crash.

full analysis.  This allows attribute syntax to be checked independently
of the full thread safety analysis.  Also introduces a new warning for the
case where a string is used as a lock expression; this allows the analysis
to gracefully handle expressions that would otherwise cause a parse error.
