[llvm] r246541 - [ARM] Turn on by default interleaved access vectorization

[Evgenii Stepanov via llvm-commits]

Hi,

this is breaking bootstrap on armv7-linux-androideabi.

http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux/builds/20039/steps/build%20llvm-symbolizer%20android%2Farm/logs/stdio

I'm working on a minimized test case.
Please consider reverting.
