[boost] [Proto] Errors due to narrowing conversions in matches.hpp

Some tests of Boost.Phoenix fail on clang trunk in a C++11 mode
due to narrowing conversions of non-type template arguments,
which are prohibited in C++11.

Specifically, the narrowing conversions occur at Line 354 and 363
in boost/proto/matches.hpp.
They can be simply resolved using `static_cast<bool>(...)`.
