1c091db526 add ::drop_back() and ::drop_front() methods, which are like pop_front/pop_back on a vector, but a) aren't destructive to "this", and b) can take a # elements to drop.

4004b18f94 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.

77f9c9f719 Switch StringMap from an array of structures to a structure of arrays. 
- -25% memory usage of the main table on x86_64 (was wasted in struct padding).

c8e6351626 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.

0339ff36c1 Make GCC happy by using makeAraryRef instead of the implicit conversion. 
I have no idea why GCC can't cope with the implicit conversion and Clang
can, or whose bug it is. Grr.

1cf4d2d1ae 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!

431b43fdbe 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.

stats output only when the event has occurred.

311fcc9b92 Add NativeClient operating system support. 
This patch adds support of NativeClient (*-*-nacl) OS support to LLVM.
It's already supported in autoconf/config.sub.

The motivation for this change is to start upstreaming PNaCl work. The
whole set of patches include llvm backends (i686, x86_64, ARM),
llvm-gcc (probably, would not be upstreamed because it's deprecated)
and clang (the work has been just started, the amount of changes is
going to be low and the most of the work is expected to be done close
to the mainline).

ec2b25406c Fix an obscure bug in PointerUnion that would bite PointerUnion3/4. Basically, 
when checking isNull(), we'd pick off the sentinel bit for the outer 
PointerUnion, but would not recursively convert the inner pointerunion to bool,
so if *its* sentinel bit is set, isNull() would incorrectly return false.

No testcase, because someone hit this when they were trying to refactor code
to use PointerUnion3, but they since found a better solution.
