I believe the removed assert in CheckerManager says it best:
InlineCall is a special hacky callback to allow intrusive
evaluation of the call (which simulates inlining). It is
currently only used by OSAtomicChecker and should go away
at some point.
OSAtomicChecker has gone away; inlineCall can now go away as well!

When suggesting "foo::bar" as a correction for "fob::bar" we mistakenly
replaced only "bar" with "foo::bar" producing "fob::foo::bar" which was broken.
This corrects that replacement in as many places as I could find & provides
test cases for all those cases I could find a test case for. There are a couple
that don't seem to be reachable (one looks entirely dead, the other just
doesn't seem to ever get called with a namespace to namespace change).

For 64-bit PowerPC SVR4, an aggregate containing only one
floating-point field (float, double, or long double) must be passed in
a register as though just that field were present. This patch
addresses the issue during Clang code generation by specifying in the
ABIArgInfo for the argument that the underlying type is passed
directly in a register. The included test case verifies flat and
nested structs for the three data types.

This only applies if the type has a name. (we could potentially do something
crazy with decltype in C++11 to qualify members of unnamed types but that
seems excessive)
It might be nice to also suggest a fixit for "&this->i", "&foo->i",
and "&foo.i" but those expressions produce 'bound' member functions that have
a different AST representation & make error recovery a little trickier. Left
as future work.

now unused static helper function.
The test case needs to be remove temporarily until I can better filter memory
operands that aren't actual variable reference.

This is a "safe" pattern, or at least one that cannot be helped by using
a strong local variable. However, if the single read is within a loop,
it should /always/ be treated as potentially dangerous.

Previously, [foo weakProp] was not being treated the same as foo.weakProp.
Now, for every explicit message send, we check if it's a property access,
and if so, if the property is weak. Then for every assignment of a
message, we have to do the same thing again.
This is a potentially expensive increase because determining whether a
method is a property accessor requires searching through the methods it
overrides. However, without it -Warc-repeated-use-of-weak will miss cases
from people who prefer not to use dot syntax. If this turns out to be
too expensive, we can try caching the result somewhere, or even lose
precision by not checking superclass methods. The warning is off-by-default,
though.

The ASTUnit needs to initialize an ASTWriter at the beginning of
parsing to fully handle serialization of a translation unit that
imports modules. Do this by introducing an option to enable it, which
corresponds to CXTranslationUnit_ForSerialization on the C API side.
