Fix regression introduced by r82198 that caused functions/methods with invalid CFGs to get analyzed.

pruning of diagnostics that may be emitted multiple times.  This is
accomplished by adding FoldingSet profiling support to PathDiagnostic,
and then having BugReporter record what diagnostics have been issued.

This was motived to a serious bug introduced by moving the
'divide-by-zero' checking outside of GRExprEngine into a separate
'Checker' class.  When analyzing code using the '-fobjc-gc' option, a
given function would be analyzed twice, but the second time various
"internal checks" would be disabled to avoid emitting multiple
diagnostics (e.g., "null dereference") for the same issue.  The
problem is that such checks also effect path pruning and don't just
emit diagnostics.  This resulted in an assertion failure involving a
real divide-by-zero in some analyzed code where we would get an
assertion failure in APInt because the 'DivZero' check was disabled
and didn't prune the logic that resulted in the divide-by-zero in the
analyzer.

The implemented solution is somewhat of a hack, and may not perform
extremely well.  This will need to be cleaned up over time.

As a regression test, 'misc-ps.m' has been modified so that its tests
are run using -fobjc-gc to test this diagnostic pruning behavior.

PCH: When writing PCH files, tweak the predicate function deciding whether to mark a decl as "external" to be closer to reality. 

This still isn't perfect, but I believe it is conservatively accurate at marking decls which IRgen needs to see, while still keeping the "deserialization footprint" on Cocoa.h.

llvm-svn: 82112

PCH: When deserializing an explicit "external definition", don't pass it to HandleTopLevelDecl -- this is already being done inside the reader.

This is something of a hack, since whether the reader actually did this depends on the "isConsumerInterestedIn" predicate. I think we need to rework how this works, but I need to discuss with Doug.

order because it was doing so while iterating over a densemap.

There are still similar problems in other places, for example 
WeakUndeclaredIdentifiers is still written to the PCH file in a nondeterminstic
order, and we emit warnings about #pragma weak in nondeterminstic order.

directly in the AST.  The current thinking is to create these
only in C++ mode for efficiency.  But for now, they're not being
created at all; patch to follow.

This will let us do things like verify that tags match during
template instantation, as well as signal that an elaborated type
specifier was used for clients that actually care.

Optimally, the TypeLoc hierarchy should be adjusted to carry tag
location information as well.
