This actually was caught by existing tests but those tests were disabled
with an XFAIL because of PR20736. While working on fixing that,
I noticed the test failure, and tracked it down to this.

We even have a really nice Clang warning that would have caught this but
it isn't enabled in LLVM! =[ I may look at enabling it.

GlobalDCE deletes global vars and updates their initializers to nullptr
while leaving underlying constants to be cleaned up later by its uses.
The clean up may never happen, fix this by forcing it every time it's
safe to destroy constants.

Replace 'noexcept' with '_NOEXCEPT' in <shared_mutex>. This allows us to build the dylib with MSVC, which doesn't support noexcept (sheesh\!). Thanks to K-ballo for the report.

This patch adds support to recognize division by uniform power of 2 and modifies the cost table to vectorize division by uniform power of 2 whenever possible.
Updates Cost model for Loop and SLP Vectorizer.The cost table is currently only updated for X86 backend.

of the class, because that's not where they live.

This means we no longer reject real ODR violations with friend declarations,
but we weren't consistently doing so anyway.

This was added in r134994, to fix a memory leak;
three days later, r135248 switched
ContainedTys from being new-allocated to being allocated
via BumpPtrAllocator, and the earlier fix was never
reverted.

The destructor doesn't seem to ever actually be called
on Types anyway, so it's harmless, but if it were,
this'd be an invalid pointer.

This reverts r134994.
