Add an attribute __python_api_test__ (set to True) to the @python_api_test decorated
test method to distinguish them from the lldb command line tests.

registers for a given virtual register.
Reserved registers are filtered from the allocation order, and any valid hint is
returned as the first suggestion.
For target dependent hints, a number of arcane target hooks are invoked.

QualType::getTypePtr(). It turns out that
cast_or_null/dyn_cast_or_null don't actually use simplify_type, so
they're guaranteed to operator on non-NULL QualType or CanQualType
objects.
Good for a 0.6% win on 403.gcc's combine.c with -emit-llvm.

We should not substitute template types if the template has a dependent
context because the template argument stack is not yet fully formed.
Instead, defer substitution until the template has a non-dependent
context (i.e. instantiation of an outer template).

common base for ExtQuals and Type that stores the underlying type
pointer. This results in a 2% performance win for -emit-llvm on a
typical C file, with 1% memory growth in the AST.
Note that there is an API change in this optimization:
QualType::getTypePtr() can no longer be invoked on a NULL
QualType. If the QualType might be NULL, use
QualType::getTypePtrOrNull(). I've audited all uses of getTypePtr() in
the code base and changed the appropriate uses over to
getTypePtrOrNull().
A future optimization opportunity would be to distinguish between
cast/dyn_cast and cast_or_null/dyn_cast_or_null; for the former, we
could use getTypePtr() rather than getTypePtrOrNull(), to take another
branch out of the cast/dyn_cast implementation.

space better. Remove this reference. To make that work, change some APIs
(most importantly, getDesugaredType()) to take an ASTContext& if they
need to return a QualType. Simultaneously, diminish the need to return a
QualType by introducing some useful APIs on SplitQualType, which is
just a std::pair<const Type *, Qualifiers>.

increasing the required type alignment from 8 to 16. This provides a
2.5% speedup for -fsyntax-only on a token-cached Cocoa.h, while only
increasing memory consumption in the ASTContext by 0.8%.

visibility. Fixes PR8713.
I've disabled a test which was testing that you can #pragma pop visibility
to get out of a namespace's visibility attribute. We should probably just
diagnose that as an error unless it's instrumental to someone's system
headers.

information. Previously, "operator[]" was not
being recognized because the detector was looking
for "operator " as a prefix. Now we handle both
cases.
