validate that we didn't override the contents of any of such files.

If this is detected, emit a diagnostic error and recover gracefully
by using the contents of the original file that the PCH was built from.

performing the search for overridden methods. We very rarely see the
same container twice, and in those rare cases we still have the
fallback of the second SmallPtrSet to eliminate duplicates. Good for
~1.5% -fsyntax-only speedup on the code in <rdar://problem/11004361>.

should be MasterPlans that want to stay on the plan stack.  So make all plans NOT
MasterPlans by default and then have the SB API's and the CommandObjectThread step
commands set this explicitly.

Also added a "clean up" phase to the Thread::ShouldStop so that if plans get stranded
on the stack, we can remove them.  This is done by adding an IsPlanStale method to the
thread plans, and if the plan can know that it is no longer relevant, it returns true,
and the plan and its sub-plans will get discarded.

There are no tests for this yet because I still need to finish the
YAML -> COFF converter so we don't get binary files checked in.

Some of the NSAssert macros in OS X 10.7 are implemented in a way that
adds extra arguments that trigger the -Wformat-extra-args warning.
Earlier versions of clang failed to detect those -Wformat issues, but now
that clang is reporting those problems, we need to quiet them since there's
nothing to be done to fix them.  <rdar://problem/11317765>

I don't know how to write a testcase for this.  Suggestions welcome.

can be used to suppress the warning in the case of intentional fallthrough.

The handling of C++11 attribute namespaces in this patch is temporary, and will
be replaced with a cleaner mechanism in a subsequent patch.

Enforcing this general practice, which keeps the analyzer less
noisy, in the CString Checker. This change suppresses "Assigned value is
garbage or undefined" warning in the added test case.

Many register classes only have a few super-registers, so it is not
necessary to keep individual bit masks for all possible sub-register

[analyzer] Equality ops are like relational ops in that the arguments shouldn't be converted to the result type. Fixes PR12206 and dupe PR12510.
