[LV] Change loops' interleave count computation
A set of microbenchmarks in llvm-test-suite (https://github.com/llvm/llvm-test-suite/pull/56), when tested on a AArch64 platform, demonstrates that loop interleaving is beneficial in two cases:
1) when TC > 2 * VW * IC, such that the interleaved vectorized portion of the loop runs at least twice
2) when TC is an exact multiple of VW * IC, such that there is no epilogue loop to run
where, TC = trip count, VW = vectorization width, IC = interleaving count
We change the interleave count computation based on this information but we leave it the same when the flag InterleaveSmallLoopScalarReductionTrue is set to true, since it handles a special case (https://reviews.llvm.org/D81416).
The initial tests were submitted from PR in https://github.com/llvm/llvm-project/pull/70272.
