Fedor Sergeev 2f9c8a0c1d [LoopUnroll] allow customization for new-pass-manager version of LoopUnroll ...

Unlike its legacy counterpart new pass manager's LoopUnrollPass does
not provide any means to select which flavors of unroll to run
(runtime, peeling, partial), relying on global defaults.

In some cases having ability to run a restricted LoopUnroll that
does more than LoopFullUnroll is needed.

Introduced LoopUnrollOptions to select optional unroll behaviors.
Added 'unroll<peeling>' to PassRegistry mainly for the sake of testing.

PowerPC

The cost of splitting a large vector instruction is not being taken into account by the getUserCost function. This was leading to some loops being over unrolled. The cost of a vector instruction is now being multiplied by the cost of the type legalization. This will return a more accurate cost.
