[cfe-commits] Patch - String literal UCN conversion should use post-concatenation string type

When a multiple piece string literal is parsed by clang, each piece
performs UCN conversion depending whether it was written as "" or L"".
This means the "" are converted using UTF-8 and the L"" are converted
using UTF-16 or UTF-32 depending on the size of wchar_t. When a narrow
string and wide string are concatenated, the final string is a wide
string. So if you put a UCN in the part declared as narrow you can end
up with UTF-8 data in a wide string.
This patch fixes this by using the final type of the string to do UCN
