llvm dev - Apr 2019 - RFC: Add option for interleaved loops, for loop vectorize.

The new pass manager uses `LoopInterleaving` to control interleaving in
LoopVectorize after: https://reviews.llvm.org/D59723.
The legacy pass manager uses `DisableUnrollLoops`.

This is a proposal to have the legacy pass manager add a corresponding
`LoopsInterleaved` field:
https://reviews.llvm.org/D61030
Clang change:
https://reviews.llvm.org/D61142

The intention is for the above two changes to not be a visible change for
clang.
A separate clang flag that controls `LoopsInterleaved` can be introduced in
follow-up patches.

Comments very welcome!

Thank you,
Alina
