Most Neon shift intrinsics do not have variants for polynomial types, but
vsri_n and vsli_n do support them, and we need to properly range-check the
shift immediates for them.

AliasAnalysis consumers, PartialAlias will be treated as MayAlias.

For AliasAnalysis chaining, MayAlias says "procede to the next analysis".
PartialAlias will be used to indicate that the query should terminate,
even though it didn't reach MustAlias or NoAlias.

Alignments smaller than the total size of the memory being loaded or stored,
unless the alignment is 8 bytes, are not allowed.  Add tests for this, too.

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%.
