r331299 - Fix bogus MSVC char8_t mangling.

[Richard Smith via cfe-commits]

New Revision: 331299

URL: http://llvm.org/viewvc/llvm-project?rev=331299&view=rev
Log:
Fix bogus MSVC char8_t mangling.

This appears to have been caused by a bad automatic svn merge with r330225
attaching the 'case' label to the wrong block of code. :(
