[analyzer] Teach FindLastStoreBRVisitor to understand stores of the same value.

Consider this case:

  int *p = 0;

  *p = 1;

If we inline 'getPointerThatMayBeNull', we might know that the value of 'p'
is NULL, and thus emit a null pointer dereference report. However, we
usually want to suppress such warnings as error paths, and we do so by using
FindLastStoreBRVisitor to see where the NULL came from. In this case, though,
because 'p' was NULL both before and after the assignment, the visitor
would decide that the "last store" was the initialization, not the
re-assignment.

This commit changes FindLastStoreBRVisitor to consider all PostStore nodes
that assign to this region. This still won't catches changes made directly
by checkers if they re-assign the same value, but it does handle the common
case in user-written code and will trigger ReturnVisitor's suppression
machinery as expected.

[analyzer] If a struct has a partial lazy binding, its fields aren't Undef.

This is essentially the same problem as r174031: a lazy binding for the first
field of a struct may stomp on an existing default binding for the
entire struct. Because of the way RegionStore is set up, we can't help
but lose the top-level binding, but then we need to make sure that accessing
one of the other fields doesn't come back as Undefined.

In this case, RegionStore is now correctly detecting that the lazy binding
we have isn't the right type, but then failing to follow through on the
implications of that: we don't know anything about the other fields in the
aggregate. This fix adds a test when searching for other kinds of default
values to see if there's a lazy binding we rejected, and if so returns
a symbolic value instead of Undefined.

Refine SourceManager's isBeforeInTranslationUnit() cache to have more entries.

isBeforeInTranslationUnit() uses a cache to reduce the expensive work
to compute a common ancestor for two FileIDs.  This work is very
expensive, so even caching the latest used FileIDs was a big win.
A closer analysis of the cache before, however, shows that the cache
access pattern would oscillate between a working set of FileIDs, and
thus caching more pairs would be profitable.

This patch adds a side table for extending caching.  This side table
is bounded in size (experimentally determined in this case from
a simple Objective-C project), and when the table gets too large
we fall back to the single entry caching before as before.

reduces -fsyntax-only time on SKTGraphicView.m by 5%.  This is
