Added the v8::jscre namespace around the jscre functions to avoid link errors...

src/third_party/jscre/pcre.h

 /* This is the public header file for JavaScriptCore's variant of the PCRE
 library. While this library started out as a copy of PCRE, many of the
 features of PCRE have been removed. This library now supports only the
 regular expression features required by the JavaScript language
 specification, and has only the functions needed by JavaScriptCore and the
 rest of WebKit.
