Subject: [PATCH] constexpr std::string_view -> const std::string_view

This works around gcc 7.2/clang rC347417 which have a bad interaction with libstdc++'s implementation of P0426
constexpr std::string_view also emits a string_view object in .rodata that cannot be optimized out by clang (which means larger object file size)

So use good old const.
