Use an accessor function for general_symbol_info::language

Also renames the member variable to m_language to make code easier to read
when more functions become member functions.

I was originally hoping to eventually make m_language private (after a few
more patches), but unfortunately then it no longer counts as a POD type,
which means gdbsupport/poison.h won't let us use memset to initialize
this type, which psymtabs rely on to clear padding bytes so that bcache
can work properly.
