fix formatting.

Do not reuse the debug location of the return value's store if there is autorelease code to be emitted between store and return instructions. This is analoguous to what we do for lexical scope cleanups.

[analyzer] Don't crash if a block's signature just has the return type.

It is okay to declare a block without an argument list: ^ {} or ^void {}.
In these cases, the BlockDecl's signature-as-written will just contain
the return type, rather than the entire function type. It is unclear if
this is intentional, but the analyzer shouldn't crash because of it.

Fix potential infinite loop when iterating over redeclarations of an ObjMethodDecl, resulting from invalid code.

Check for invalid decls in ObjCMethodDecl::getNextRedeclaration(); otherwise if we start from an invalid redeclaration
of an @implementation we would move to the @interface and not reach the original declaration again.

Fix PR16060.

The testcase in PR16060 points out that while template arguments can
show that a type is not externally visible, the standards still says
they have external linkage.

In terms of our implementation, it means that we should merge just the
isExternallyVisible bit, not the formal linkage.

Revert "[analyzer; alternate edges] don't add an edge incoming from the start of a function"

...and make this work correctly in the current codebase.

After living on this for a while, it turns out to look very strange for
inlined functions that have only a single statement, and somewhat strange
for inlined functions in general (since they are still conceptually in the
middle of the path, and there is a function-entry path note).

It's worth noting that this only affects inlined functions; in the new
arrow generation algorithm, the top-level function still starts at the
first real statement in the function body, not the enclosing CompoundStmt.

This reverts r182078 / dbfa950abe0e55b173286a306ee620eff5f72ea.

Objective-C: Implements gcc's -Wselector option
which diagnoses type mismatches of identical

fixes a comment in my last patch.

Walk over MaterializeTemporaryExpr when reverting an initializer to its
syntactic form in template instantiation. Previously, this blocked the
reversion and we ended up losing inner CXXBindTemporaryExprs (and thus
forgetting to call destructors!).

[PCH] Fix crash with valid code, related to anonymous field initializers.

In a certain code-path we were not deserializing an anonymous field initializer correctly,
leading to a crash when trying to IRGen it.

This is a simpler version of a patch by Yunzhong Gao!

[analyzer] Add --override-compiler option to scan-build.

The new advanced option ensures ccc-analyze is used even when better
interposition methods are available.

Fix handling of braced-init-list as reference initializer within aggregate
initialization. Previously we would incorrectly require an extra set of braces
around such initializers.
