* [libc++] Shrink variant's index type when possibleEric Fiselier2017-11-191-0/+68
| | | | | | | | | | | | | | | | | | | Summary: Currently `std::variant` always uses an unsigned int to store the variant index. However this isn't nessesary and causes `std::variant` to be larger than it needs to be in most cases. This patch changes the index type to be `unsigned char` when possible, and `unsigned short` or `unsigned int` otherwise, depending on the size (Although it's questionable if it's even possible to create a variant with 65535 elements. Unfortunately this change is an ABI break, and as such is only enabled in ABI v2.

* Implement LWG 3013 - some filesystem members should not be noexcept.Eric Fiselier2017-10-306-21/+32
| | | | | | | | | | | | | | | LWG 3013 points out that the constructors and increment members of the directory iterators need to allocate, and therefore cannot be marked noexcept. It also points out that `is_empty` and `copy` likely need to allocate as well, and as such can also not be noexcept. This patch speculatively implements the resolution removing noexcept, because libc++ does indeed have the possibility of throwing on allocation failure. llvm-svn: 316941
