Tests relying on this should explicitly use -passes='require<analysis>,foo'.

As LoopPredication performs non-equivalent transforms removing some
checks from loops, other passes may not be able to perform transforms
they'd be able to do if the checks were left in loops.

This patch makes LoopPredication insert assumes of the replaced
conditions either after a guard call or in the true block of
widenable condition branch.

Upon further investigation and discussion,
this is actually the opposite direction from what we should be taking,
and this direction wouldn't solve the motivational problem anyway.

Additionally, some more (polly) tests have escaped being updated.
So, let's just take a step back here.

This reverts commit f3190dedeef9da2109ea57e4cb372f295ff53b88.

Since LICM has now unconditionally moved to MemorySSA based form, all
passes that run in same LPM as LICM need to preserve MemorySSA (i.e. our
downstream pipeline).

Added loop-mssa to all tests and perform -verify-memoryssa within
LoopPredication itself.
