Florian Hahn 2e03213f90 [LoopVersioning] Require loop-simplify form for loop versioning.
Summary:
Requiring loop-simplify form for loop versioning ensures that the
runtime check block always dominates the exit block.
    
This patch closes #30958 (https://llvm.org/bugs/show_bug.cgi?id=30958).

Adam Nemet 9bfbf8bbdf [LV] Stop saying "use -Rpass-analysis=loop-vectorize"
This is PR28376.

Unfortunately given the current structure of optimization diagnostics we
lack the capability to tell whether the user has
passed -Rpass-analysis=loop-vectorize since this is local to the
front-end (BackendConsumer::OptimizationRemarkHandler).

So rather than printing this even if the user has already
passed -Rpass-analysis, this patch just punts and stops recommending
this option.  I don't think that getting this right is worth the
complexity.

Michael Kuperstein 5185b7dde3 [LV] Remove triples from target-independent vectorizer tests. NFC.
Vectorizer tests in the target-independent directory should not have a target
triple. If a test really needs to query a specific backend, it belongs in the
right target subdirectory (which "REQUIRES" the right backend). Otherwise, it
should not specify a triple.
