Subject: Move libc++ pair/tuple assign test to libcxx/ test directory.
X-Git-Tag: llvmorg-7.0.0-rc1~9419
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=f8aa23879e4719fbb040c59276dfec8f4854f9a1;p=platform%2Fupstream%2Fllvm.git

Move libc++ pair/tuple assign test to libcxx/ test directory.

Libc++ implements the pair& operator=(pair<U, V>) assignment operator
using a single template that handles assignment from all tuple-like types.

This patch moves the test for that to the libcxx test directory since
it's non-standard. It also adds additional tests to the std/.../pair
directory to test the standard behavior this template implements.
