MFC r312993:

Pull in r279454 from upstream llvm trunk (by James Molloy):

  [SROA] Remove incorrect assertion

  Confirmed with aprantl, this assertion is incorrect - code can get
  here (for example 80-bit FP types) and if it does it's benign. This
  is exposed by a completely unrelated patch of mine, so stop the
  compiler falling over.

  Original differential: http://reviews.llvm.org/D16187
  aprantl's advice to remove assertion:
  http://lists.llvm.org/pipermail/llvm-commits/Week-of-Mon-20160815/382129.html

This should fix assertions when building the math/opensolaris-libm port.
