Add checks before hoisting out in loop pipelining (#90872)
Currently, during a loop pipelining transformation, operations may be
hoisted out without any checks on the loop bounds, which leads to
incorrect transformations and unexpected behaviour. The following [issue
](https://github.com/llvm/llvm-project/issues/90870) describes the
problem more extensively, including an example.
The proposed fix adds some check in the loop bounds before and applies
the maximum hoisting.
