Remove copy and copy assignment rather than have them as private declarations.
They are superfluous given the move and move assignment.
As a drive-by, also specialize `std::hash` without reopening `namespace std`.

Detected by evil-izing the widely used `MoveOnly` testing type.
I had to patch some tests that were themselves using its comma operator,
but I think that's a worthwhile cost in order to catch more places
in our headers that needed comma-proofing.
The trick here is that even `++ptr, SomeClass()` can find a comma operator
by ADL, if `ptr` is of type `Evil*`. (A comma between two operands
of non-class-or-enum type is always treated as the built-in
comma, without ADL. But if either operand is class-or-enum, then
ADL happens for _both_ operands' types.)

... so that comparisons with an `int` LHS and `MoveOnly` RHS are valid, as is necessary for the `partial_sort_copy` test to pass with an implementation that doesn't force a conversion to the type of the RHS as libc++ does.
Summary: a4b8ee6 made all MoveOnly members constexpr but, some members and constructors contain expressions that are only valid in C++14 and later. This patch prefixes those methods and constructors with TEST_CONSTEXPR_CXX14.

to reflect the new license. These used slightly different spellings that
defeated my regular expressions.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.
