6f72ac4799 Add various coarse bit-width architecture predicates to llvm::Triple. 
These are very useful for frontends and other utilities reasoning about
or selecting between triples.

ff5bad0787 Add portable bit mask operations to BitVector. 
BitVector uses the native word size for its internal representation.
That doesn't work well for literal bit masks in source code.

This patch adds BitVector operations to efficiently apply literal bit
masks specified as arrays of uint32_t.  Since each array entry always
holds exactly 32 bits, these portable bit masks can be source code
literals, probably produced by TableGen.

1243cdda63 As Doug pointed out (and I really should know), it is perfectly easy to 
make VariadicFunction actually be trivial. Do so, and also make it look
more like your standard trivial functor by making it a struct with no
access specifiers. The unit test is updated to initialize its functors
properly.

can, or whose bug it is. Grr.

d916ce3c8e Add a generic collection of class templates to ADT for building 
variadic-like functions in C++98. See the comments in the header file
for a more detailed description of how these work. We plan to use these
extensively in the AST matching library. This code and idea were
originally authored by Zhanyong Wan. I've condensed it using macros
to reduce repeatition and adjusted it to fit better with LLVM's ADT.

Thanks to both David Blaikie and Doug Gregor for the review!

e15402f92b Change the Dominators recalculate() function to only rely on GraphTraits 
This is a patch by Guoping Long!

As part of utilizing LLVM Dominator computation in Clang, made two changes to LLVM dominators tree implementation:

 - (1) Change the recalculate() template function to only rely on GraphTraits.
 - (2) Add a size() method to GraphTraits template class to query the number of nodes in the graph.
