[Demangle] use std::string_view::data rather than &*std::string_view::begin
To fix expensive check builds that were failing when using MSVC's
std::string_view::iterator::operator*, I added a few expressions like
&*std::string_view::begin. @nico pointed out that this is literally the
same thing and more clearly expressed as std::string_view::data.
