[PATCH] Recognize dwarf::DW_ATE_UTF in DwarfUnit isUnsignedDIType

[Stephan Tolksdorf]

Hi dblaikie,

This patch fixes an assert violation triggered by the following clang test case:

  // compile with -std=c++11 -g
  const char16_t c = 0;
  char16_t test() { return c; }

David, you wrote you could help me turn this into an LLVM test case?
