clang -cc1 logic for running an action against a set of options.
 - This should make it easier to build tools that have a clang -cc1 like
   interface, but aren't actually part of clang -cc1.

It was only being used by instructions with the t_addrmode_sp addressing mode,
and that is pattern matched in a way that guarantees SP is used. There is
never any register allocation done from this class.

flag doesn't exist there, and this is an x86 test.

Add a quick pass to optimize sign / zero extension instructions. For targets where the pre-extension values are available in the subreg of the result of the extension, replace the uses of the pre-extension value with the result + extract_subreg.

For now, this pass is fairly conservative. It only perform the replacement when both the pre- and post- extension values are used in the block. It will miss cases where the post-extension values are live, but not used.

why the candidate is non-viable.  There's a lot we can do to improve this, but
it's a good start.  Further improvements should probably be integrated with the
bad-initialization reporting routines.

Make method definitions in TUVisitor out-of-line, making it easy to tell what visitor methods are defined.
Generalize TUVisitor to take a general "root" and "iterator" callback; this is prep. work to merging TUVisitor and CDeclVisitor.

do better here. Fixes <rdar://problem/7513023>.

actually be evaluated at runtime.

name a template, when they occur in a base-specifier. This is one of
the (few) places where we know for sure that an identifier followed by
a '<' must be a template name, so we can diagnose and recover well:

test/SemaTemplate/dependent-base-classes.cpp:9:16: error: missing
'template'
      keyword prior to dependent template name 'T::apply'
struct X1 : T::apply<U> { }; // expected-error{{missing 'template' ...

               template 
test/SemaTemplate/dependent-base-classes.cpp:12:13: error: unknown

      'vector'
struct X2 : vector<T> { }; // expected-error{{unknown template name
'vector'}}

in JT.

2) When cloning blocks for PHI or xor conditions, use
instsimplify to simplify the code as we go.  This allows us to 
squish common cases early in JT which opens up opportunities for
subsequent iterations, and allows it to completely simplify the
testcase.
