Fix Clang install rules to not set permissions on include/

The CMake install(DIRECTORY) command documents that it sets permissions
on directories it is asked to install.  Since the <prefix>/include
directory may not be exclusive to the LLVM/Clang installation, we should
not ask CMake to manage permissions of that directory for us.  Instead,
give only our own include/clang and include/clang-c subdirectories to
the install(DIRECTORY) command.

Fixes PR4500. Patch by Brad King.

ARM: implement vshrn NEON intrinsic in terms of shr/trunc

Now the backend supports the natural LLVM IR, we can shamelessly steal the
AArch64 front-end code to implement the vshrn intrinsic on 32-bit ARM.

ARM: move vshll NEON implementation to common code

Now that both ARM backends use the same implementation for vshll operations,

case where a pragma would have a side effect but is ignored.

MS ABI: Add support for #pragma pointers_to_members

Introduce a notion of a 'current representation method' for
pointers-to-members.

When starting out, this is set to 'best case' (representation method is
chosen by examining the class, selecting the smallest representation
that would work given the class definition or lack thereof).

This pragma allows the translation unit to dictate exactly what
representation to use, similar to how the inheritance model keywords
operate.

N.B.  PCH support is forthcoming.

Fix PCH deserialization bug with local static symbols being treated as local extern.

This triggered a miscompilation of code using Boost's function_template.hpp
when it was included inside a PCH file.  A local static within
that header would be treated as local extern, resulting in the wrong
mangling.  This only occurred during PCH deserialization.

Fixes <rdar://problem/15975816> and <rdar://problem/15926311>.

AAPCS: Do not split structs after CPRC allocated on stack

According to the AAPCS, we can split structs between GPRs and the stack,
except for when an argument has already been allocated on the stack. This
can occur when a large number of floating-point arguments fill up the VFP
registers, and are alllocated on the stack before the general-purpose argument
registers are full.
