7f59a88431 Fixed a problem that UBSAN found, where we were calling memcmp(null, p, 0) - which is undefined behavior

1cf810b81b Replaced checking in string_view::remove_suffix/remove_prefix by _LIBCPP_ASSERT, since this is technically undefined behavior. Fixes PR#21496

b9536101dc NFC. Move definition of _LIBCPP_ASSERT into __debug header and remove external include guards. 
Things done in this patch:

1. Make __debug include __config since it uses macros from it.

2. The current method of defining _LIBCPP_ASSERT is prone to redefinitions. Move
the null _LIBCPP_ASSERT definition into the __debug header to prevent this.

3. Remove external <__debug> include gaurds. <__debug> guards almost all of its
contents internally. There is no reason to be doing it externally.

This patch should not change any functionality.

484728789e string_view enhancements. Move to the correct namespace. Better constexpr support (thanks to Richard for the suggestions). Update the tests to match this. Add <experimental/__config for experimental macros/etc to live.

164b297099 Implement string_view from the library fundamentals TS (n4023). Also works in C++11 and 03, with reduced functionality (mostly in the area of constexpr)
