- This fast path is almost 100% effective on real code, and lets us avoid
multiple allocations of 128-bit APSInt objects in the common case.
- As with any overflow-check-skipping-code, I'd appreciate someone double
checking my logic.

This reverts commit r177158.
I'm blindly reverting this because it appears to be breaking numerous
buildbots. I'll reapply if it doesn't turn out to be the culprit.

the balance between expected behavior and compatibility with the gdb

(GDB gets confused if we break an expression into multiple debug
stmts so we enable this behavior only for inlined functions. For the
full experience people can still use -gcolumn-info.)

FindNodeOrInsertPos() is called 10 lines earlier already, and the function
early-returns there if the result is != 0. InsertPos isn't recomputed after
that check, so this assert is always trivially true. (And it has nothing to
do with if T is canonical or not.)

This created 2 issues:
1) Performance issue, since typo-correction with PCH/modules is rather expensive.
2) Correctness issue, since if it managed to "correct" 'super' then bogus compiler errors would
be emitted, like this:
3.m:8:3: error: unknown type name 'super'; did you mean 'super1'?
super.x = 0;
^~~~~
super1
t3.m:5:13: note: 'super1' declared here
typedef int super1;
^
t3.m:8:8: error: expected identifier or '('
super.x = 0;

sure it attaches in the given edge case
In the test case below, the value V is not constrained to 0 in ErrorNode but it is in node N.
So we used to fail to register the Suppression visitor.
We also need to change the way we determine that the Visitor should kick in because the node N belongs to
the ExplodedGraph and might not be on the BugReporter path that the visitor sees. Instead of trying to match the node,
turn on the visitor when we see the last node in which the symbol is ‘0’.

This yields a log(#ast_nodes) worst-case improvement with matchers like
stmt(unless(hasAncestor(...))).
Also made the order of visitation for ancestor matches BFS, as the most
common use cases (for example finding the closest enclosing function

template instantiation will still consider them to be definitions
if we instantiate the containing class before we get around
to parsing the friend.
This seems like a legitimate use of "late template parsed" to me,
but I'd appreciate it if someone responsible for the MS feature
would look over this.
This file already appears to access AST nodes directly, which
is arguably not kosher in the parser, but the performance of this
path matters enough that perpetuating the sin is justifiable.
Probably we ought to reconsider this policy for very simple
manipulations like this.
The reason this entire thing is necessary is that
function template instantiation plays some very gross games
in order to not associate an instantiated function template
with the class it came from unless it's a definition, and
the reason *that's* necessary is that the AST currently
cannot represent the instantiation history of individual
function template declarations, but instead tracks it in
common for the entire function template. That probably
prevents us from correctly reporting ill-formed calls to
ambiguously instantiated friend function templates.

Before this patch we would compute the linkage lazily and cache it. When the
AST was modified in ways that could change the value, we would invalidate the
cache.
That was fairly brittle, since any code could ask for the a linkage before
the correct value was available.
We should change the API to one where the linkage is computed explicitly and
trying to get it when it is not available asserts.
This patch is a first step in that direction. We still compute the linkage
lazily, but instead of invalidating a cache, we assert that the AST
modifications didn't change the result.

The back-end cannot differentiate between functions that are from a .ll file and
those generated from the front-end. We cannot then take the non-precense of
these attributes as a "false" value. Have the front-end explicitly set the value
to 'true' or 'false' depending upon what is actually set.

In a module-enabled Cocoa PCH file, we spend a lot of time stat'ing the headers
in order to associate the FileEntries with their modules and support implicit
module import.
Use a more lazy scheme by enhancing HeaderInfoTable to store extra info about
the module that a header belongs to, and associate it with its module only when
there is a request for loading the header info for a particular file.

This allows resolving top-header filenames of modules to FileEntries when
we need them, not eagerly.
Note that that this breaks ABI for libclang functions
clang_Module_getTopLevelHeader / clang_Module_getNumTopLevelHeaders
but this is fine because they are experimental and not widely used yet.

When BugReporter tracks C++ references involved in a null pointer violation, we
want to differentiate between a null reference and a reference to a null pointer. In the
first case, we want to track the region for the reference location; in the second, we want
to track the null pointer.
In addition, the core creates CXXTempObjectRegion to represent the location of the
C++ reference, so teach FindLastStoreBRVisitor about it.
This helps null pointer suppression to kick in.
