Florian Hahn c6e38b928c Reapply "[LV] Improve AnyOf reduction codegen. (#78304)" ...

This reverts the revert commit 589c7abb03.

This patch includes a fix for any-of reductions and epilogue
vectorization. Extra test coverage for the issue that caused the revert
has been added in 399ff08e29.

--------------------------------
Original commit message:

Update AnyOf reduction code generation to only keep track of the AnyOf
property in a boolean vector in the loop, only selecting either the new
or start value in the middle block.

The patch incorporates feedback from https://reviews.llvm.org/D153697.

This fixes the #62565, as now there aren't multiple uses of the
start/new values.
