Tested x86_64-linux, built on msp430-elf and h8300-elf. Pushed to trunk.

For H8/300 with -msx -mn -mint32 the type of (_M_len - __pos) is int,
because int is wider than size_t so the operands are promoted.

libstdc++-v3/ChangeLog:

	* include/std/string_view (basic_string_view::copy) Use explicit
	template argument for call to std::min<size_t>.
	(basic_string_view::substr): Likewise.
