Some more correctness fixes and code-size optimizations for fragile-ABI
...
ObjC exceptions:
- don't enter a try for the catch blocks unless there's a finally
- put the setjmp buffer in the locals set for liveness reasons
- dump the sync object into an alloca in the locals set for liveness reasons
Some of this can go away if the backend starts to properly calculate liveness
in the presence of setjmp (which would also be a *much* stabler solution).

When we try (but fail) to build a precompiled preamble, wait for a
...
short "cooling off" period (defaulting to 5 reparses) before trying to
build a precompiled preamble again. Previously, if we failed to build
the precompiled preamble at any time, we just gave up the whole
charade any never tried again.

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

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.
