Reviewed by NOBODY (OOPS!).

WebKit wishes to move from UChar to the C++ standard char16_t; they are currently typedef'ed to be the same. This PR makes the textual substitutions across JavaScriptCore. This is a simple search and replace for \bUChar\b with no other changes, and it should have no functional effect.

This is one of a series of PRs for different parts of WebKit.
