match splats in the form (splat (scalar_to_vector (load ...))) whenever the load can be folded. All the logic and instruction emission is working but because of PR8156, there are no ways to match loads, cause they can never be folded for splats. Thus, the tests are XFAILed, but I've tested and exercised all the logic using a relaxed version for checking the foldable loads, as if the bug was already fixed. This should work out of the box once PR8156 gets fixed since MayFoldLoad will work as expected. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@137810 91177308-0d34-0410-b5e6-96231b3b80d8
