Commit 6e965df6054a4a6be53b3ba9ffa91ec7a0f9d072 by arthur.j.odwyer Revert "Revert "[libc++] ADL-proof <vector> by adding _VSTD:: qualification on calls."" This reverts commit 620adacf87a376ec536ccc66af59df5bb4dc3b38. Fix: unsupport C++03 for the new test, define helpers before __swap_allocator (1) Add _VSTD:: qualification to __swap_allocator. (2) Add _VSTD:: qualification consistently to __to_address. (3) Add some more missing _VSTD:: to <vector>, with a regression test. This part is cleanup after d9a4f936d05. Note that a vector whose allocator actually runs afoul of any of these ADL calls will likely also run afoul of simple things like `v1 == v2` (which is also an ADL call). But, still, libc++ should be consistent in qualifying function calls wherever possible.

Commit 79f75468b46d63f262ebda4544fd30ed8cb5a05a by Matthew.Arsenault AMDGPU: Fix counting kernel arguments towards register usage Also use DataLayout to get type size. Relying on the IR type size is also pretty broken here, since this won't perfectly capture how types are legalized.
