is general goodness because representations of member pointers are
not always equivalent across member pointer types on all ABIs
(even though this isn't really standard-endorsed).

Take advantage of the new information to teach IR-generation how
to do these reinterprets in constant initializers.  Make sure this
works when intermingled with hierarchy conversions (although
this is not part of our motivating use case).  Doing this in the
constant-evaluator would probably have been better, but that would
require a *lot* of extra structure in the representation of
constant member pointers:  you'd really have to track an arbitrary
chain of hierarchy conversions and reinterpretations in order to
get this right.  Ultimately, this seems less complex.  I also
wasn't quite sure how to extend the constant evaluator to handle
foldings that we don't actually want to treat as extended
constant expressions.

default arguments for lambda expressions.

template is defined, and then the specialization is referenced again, don't
forget to instantiate the template on the second reference. Use the source
location of the first reference as the point of instantiation, though.

* if, switch, range-based for: warn if semicolon is on the same line.
* for, while: warn if semicolon is on the same line and either next
statement is compound statement or next statement has more
indentation.

Replacing the semicolon with {} or moving the semicolon to the next
line will always silence the warning.

Tests from SemaCXX/if-empty-body.cpp merged into SemaCXX/warn-empty-body.cpp.

(In response of Ted's review of r150112.)

This moves the logic which checked if a symbol escapes through a
parameter to invalidateRegionCallback (instead of post CallExpr visit.)

To accommodate the change, added a CallOrObjCMessage parameter to
checkRegionChanges callback.

Replace the simple Levenshtein edit distance for typo correction
candidates--and the hacky way adding namespace qualifiers would affect
the edit distance--with a synthetic "edit distance" comprised of several
factors and their relative weights. This also allows the typo correction
callback object to convey more information about the viability of a
correction candidate than simply viable or not viable.

Implement new DiagnosticsRenderer that packages notes retrieved by clang_getDiagnosticSetFromTU() as
child diagnostics of primary diagnostics.  By using the DiagnosticRenderer, these Diagnostics now
match with those generated for serialized diagnostics.
