r330887 - Switch to Clang's isDigit function.

New Revision: 330887

URL: http://llvm.org/viewvc/llvm-project?rev=330887&view=rev
Log:
Switch to Clang's isDigit function.

std::isdigit can be overloaded, causing the template deduction to fail.  Use
Clang's isDigit function which to avoid this.  Switch the other calls for
consistency.
