Provide more details for DINameSpace debug info in the IR comment annotations

Sorry for the version skew - I should've committed this before the
corresponding Clang test case.

Test DW_TAG_namespace support in the backend

This is the backend portion of a Clang test case
(clang/test/CodeGenCXX/debug-info-namespace.cpp) that was roughly/coarsely
testing LLVM.

Don't assume the test directory is writable, use %T to find a writable
directory.

Reorder the DIFile parameter in DINameSpace

Moving the DIFile parameter to immediately proceed the tag so that it will be a
common prefix with other DIScopes (once the DIFile is replaced with the raw
file/directory pair).

Introduce some new statistics to help track the exact behavior of the
new SROA pass.

Move the endif to the correct line so we don't have warnings about
unused statistics variables.

[SROA] Don't preserve the IR names in release builds.

This is espcially important because the new SROA pass goes to great
lengths to provide helpful names for debugging, and as a consequence
they can become very slow to render.

Good for between 5% and 15% of the SROA runtime on some slow test cases
such as the one in PR15412.

Fix a silly search-and-replace goof with r177495 that only broke
non-release builds.

Move SDNode order propagation to SDNodeOrdering, which also fixes a missed
case of order propagation during isel.

Thanks Owen for the suggestion!

Revert "pre-RA-sched: fix TargetOpcode usage"

This reverts commit 06091513c283c863296f01cc7c2e86b56bb50d02.

The code is obviously wrong, but the trivial fix causes
inefficient code generation on X86. Somebody with more
knowledge of the code needs to take a look here.
