When re-raising an exception after a cleanup, we need to call _Unwind_Resume_or_Rethrow
...
instead of _Unwind_Resume. With SJLJ exceptions, this is spelled
"_Unwind_SjLj_Resume_or_Rethrow", not "_Unwind_SjLj_Resume", which has
significantly different semantics.
We should actually never be generating a call to _Unwind_SjLj_Resume directly;
even if we were generating true cleanups (which we aren't because of the
horrible hack), we should be calling __cxa_end_cleanup() on ARM. I
haven't implemented this because there's little point as long as the HH is
present.
I believe this fixes <rdar://problem/8281377>.

Improve our handling of user-defined conversions when computing
...
implicit conversion sequences. In particular, model the "standard
conversion" from a class to its own type (or a base type) directly as
a standard conversion in the normal path *without* trying to determine
if there is a valid copy constructor. This appears to match the intent
of C++ [over.best.ics]p6 and more closely matches GCC and EDG.
As part of this, model non-lvalue reference initialization via
user-defined conversion in overloading the same way we handle it in
InitializationSequence, separating the "general user-defined
conversion" and "conversion to compatible class type" cases.
The churn in the overload-call-copycon.cpp test case is because the
test case was originally wrong; it assumed that we should do more
checking for copy constructors that we actually should, which affected
overload resolution.
Fixes PR7055. Bootstrapped okay.

- Make ObjCInterfaceDecl redeclarable, and create separate decl nodes for forward declarations and the definition.
...
- Eagerly create ObjCInterfaceTypes for declarations.
- The two above changes lead to a 0.5% increase in memory use and no speed regression when parsing Cocoa.h. On the other hand, now chained PCH works when there's a forward declaration in one PCH and the interface definition in another.
- Add HandleInterestingDecl to ASTConsumer. PCHReader passes the "interesting" decls it finds to this function instead of HandleTopLevelDecl. The default implementation forwards to HandleTopLevelDecl, but ASTUnit's handler for example ignores them. This fixes a potential crash when lazy loading of PCH data would cause ASTUnit's "top level" declaration collection to change while being iterated.

Store inheritance paths after CastExprs instead of inside them.
...
This takes some trickery since CastExpr has subclasses (and indeed,
is abstract).
Also, smoosh the CastKind into the bitfield from Expr.
Drops two words of storage from Expr in the common case of expressions
which don't need inheritance paths. Avoids a separate allocation and
another word of overhead in cases needing inheritance paths. Also has
the advantage of not leaking memory, since destructors for AST nodes are
never run.

Correct -ftrapv to trap on errors, instead of calling the

__overflow_handler entrypoint that David Chisnall made up.
Calling __overflow_handler is not part of the contract of

in in the first place.
According to:
http://permalink.gmane.org/gmane.comp.compilers.clang.devel/8699
David is using this for some of arbitrary precision integer stuff
or something, which is not an appropriate thing to implement on
this.

Improved false positive detection and numerous small issues in UnreachableCodeChecker
...
- Reporting now uses getUnreachableStmt which returns the Stmt* we should report
- Indexing of reachable and visited blocks now use CFGBlock ID's instead of pointers
- The CFG used in the unreachable search is now the unoptimized CFG
- Added 'Dead code' category to warnings
- Removed obsolete function getCondition
- Simplified false positive detection based on properties of FindUnreachableEntryPoints

Makes GRState::makeWithStore private, to encourage clients to make store changes through GRState instead of directly accessing the StoreManager. Also adds cover methods for InvalidateRegion(s) and EnterStackFrame to GRState.
...
This is in preparation for proposed region change notifications. No functionality change.

When using a precompiled preamble, keep track of the top-level
...
declarations that we saw when creating the precompiled preamble, and
provide those declarations in addition to the declarations parsed in
the main source file when traversing top-level declarations. This
makes the use of precompiled preambles a pure optimization, rather
than changing the semantics of the parsed translation unit.

Apart from storing/retrieving the previous redeclaration from PCH, also store/retrieve the most recent
...
redeclaration. That way we are sure that the full redeclarations chain is loaded.
When using chained PCHs, first declarations point to the most recent redeclarations in the same PCH.
To address this use a REDECLS_UPDATE_LATEST record block to keep track of which first declarations need
to point to a most recent redeclaration in another PCH.

Changed GRExprEngine to pass down a reference to itself when checkers are doing postanalysis. This allows the checker to gather information about the state of the engine when it has finished.

- Exposed the worklist and BlockAborted flag in GRCoreEngine
