Pull in r201130 from upstream clang trunk (by Ted Kremenek):
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.

Synchronize the (non-default) libc++/libcxxrt C++ stack in stable/9 with
head, by merging almost all recent changes to libc++ and libcxxrt.
MFC r255206 (by theraven):
Add a c++/v1/tr1 include directory containing symlinks to all of the standard
headrs.
Lots of third-party code expects to find C++03 headers under tr1 because that's
where GNU decided to hide them. This should fix ports that expect them there.
MFC r256642:
Since C++ typeinfo objects are currently not guaranteed to be merged at
runtime by the dynamic linker, check for their equality in libcxxrt by
not only comparing the typeinfo's name pointers, but also comparing the
full names, if necessary. (This is similar to what GNU libstdc++ does
in its default configuration.) The 'deep' check can be turned off again
by defining LIBCXXRT_MERGED_TYPEINFO, and recompiling libcxxrt.
