Fix http://stackoverflow.com/questions/13521163

Don't require that, during template deduction, a template specialization type
as a function parameter has at least as many template arguments as one used in
a function argument (not even if the argument has been resolved to an exact
type); the additional parameters might be provided by default template
arguments in the template. We don't need this check, since we now implement
[temp.deduct.call]p4 with an additional check after deduction.

Use the BlockDecl captures list to infer the direct captures for a BlockDataRegion.  Fixes <rdar://problem/12415065>.

We still need to do a recursive walk to determine all static/global variables
referenced by a block, which is needed for region invalidation.

Rework the bitfield access IR generation to address PR13619 and
generally support the C++11 memory model requirements for bitfield
accesses by relying more heavily on LLVM's memory model.

The primary change this introduces is to move from a manually aligned
and strided access pattern across the bits of the bitfield to a much
simpler lump access of all bits in the bitfield followed by math to
extract the bits relevant for the particular field.

This simplifies the code significantly, but relies on LLVM to
intelligently lowering these integers.

I have tested LLVM's lowering both synthetically and in benchmarks. The
lowering appears to be functional, and there are no really significant
performance regressions. Different code patterns accessing bitfields
will vary in how this impacts them. The only real regressions I'm seeing
are a few patterns where the LLVM code generation for loads that feed
directly into a mask operation don't take advantage of the x86 ability
to do a smaller load and a cheap zero-extension. This doesn't regress
any benchmark in the nightly test suite on my box past the noise
threshold, but my box is quite noisy. I'll be watching the LNT numbers,
and will look into further improvements to the LLVM lowering as needed.
