Thank you for that background, the reasoning seems sensible to me.

Currently not supported clauses are reduction, if, linear, nontemporal and order based on my testing. Of those, with the change I just pushed, both `if` and `reduction` are ignored with a warning. The remaining 3 clauses result in either a crash or a semantics error, but that is also the case without this PR as the crash happens before the `convertOmpSimd` codepath is reached. Since that is unaffected by this PR, I think addressing it would best be done in a separate one.
