This removes some more redundant _CharT template parameters.

2013-11-08  Jonathan Wakely  <jwakely.gcc@gmail.com>

        * include/bits/regex_compiler.h (__detail::_AnyMatcher,
        __detail::_CharMatcher, __detail::_BracketMatcher): Remove redundant
        _CharT template parameters.
        * include/bits/regex_compiler.tcc: Likewise.

Tested x86_64-linux, committed to trunk.
