This is used only for keeping detailed type source information for protocol references,
it should not participate in the semantics of the type system.
Its protocol list is not canonicalized.

createBitcodeWriterPass instead of the underlying raw_ostream. This
avoids trouble with formatted_raw_ostream's behavior of setting the
underlying stream to be unbuffered, which resulted in
clang -emit-llvm -S using unbuffered output.

avoid scanning for an "entry point" FunctionDecl if we (a) have no
translation unit actions and (b) no entry point function has been
specified.

Type hierarchy. Demote 'volatile' to extended-qualifier status. Audit our
use of qualifiers and fix a few places that weren't dealing with qualifiers
quite right; many more remain.

Several of the existing methods were identical to their respective
specializations, and so have been removed entirely. Several more 'leaf'
optimizations were introduced.
The getAsFoo() methods which imposed extra conditions, like
getAsObjCInterfacePointerType(), have been left in place.

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.

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.

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.

cleaner, and fixes PR4536.

such initializations properly convert constructor arguments and fill
in default arguments where necessary. This also makes the ownership
model more clear.

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.
