[analyzer] Add a clone() method to BugReporterVisitor, so that we'll be able to reset diagnostic generation.

Avoid applying retain/release effects twice in RetainCountChecker when a function call was inlined (i.e., we do not need to apply summaries in such cases).

This makes -fsyntax-only for test/Sema/many-logical-ops.c about 32x times faster.

With measuring SemaExpr.cpp I see differences below the noise level.

"Teach" RetainCountChecker about dispatch_set_context, which can indirectly free its argument later.  Fixes <rdar://problem/11059275>.

Fix broken CFG when an initializer is a statement expression that starts with a while loop (PR 12325).

specialization is known to be incomplete. If we're asked to try to
complete it, don't attempt to instantiate it again -- that can lead
to stack overflow, and to rejects-valids if the class being incomplete
is not an error.

Specifically, we use the last store of the leaked symbol in the leak diagnostic.
(No support for struct fields since the malloc checker doesn't track those
yet.)

+ Infrastructure to track the regions used in store evaluations.
This approach is more precise than iterating the store to
obtain the region bound to the symbol, which is used in RetainCount
checker. The region corresponds to what is uttered in the code in the
last store and we do not rely on the store implementation to support
this functionality.

The getARMTargetCPU and getLLVMArchSuffixForARM functions exist in both
Toolchain.cpp and Tools.cpp.  This stuff needs a thorough overhaul.  In the
meantime, this patch at least makes them consistent.  One version had been
converted to use StringSwitch, and the other version had new Cortex M-series
processors added.

On Darwin the architecture and the corresponding Mach-O slice is typically
specified with -arch.  If not, it defaults to the current host architecture.
Do not use -mcpu to override the -arch value.  This is only an issue when
people need to use specialized code for a non-default CPU (hopefully guarded
by run-time checks to detect the current processor).  The -mcpu option is
still used for the -target-cpu option to clang, but this patch causes it to
not be used to set the architecture in the target triple.
