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.

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

This fixes a crash in audio/murmur, which is using both PCH and Boost.

Direct commit to stable/10 and stable/9, since head has clang 3.5.1,
which already includes this change.
