Hi,

This RFC is to propose relaxing the flag needed to allow the creation of 
simd clones from omp declare variants, such that we can use 
-fopenmp-simd rather than -fopenmp.
This should only change the behaviour of omp simd clones and should not 
enable any other openmp functionality, though I need to test this 
furter, for the time being I just played around a bit with some of the 
existing declare-variant tests.

Any objections to this in general? And/or ideas to properly test the 
effect of this on other omp codegen? My current plan is to have a look 
at the declare-variant tests we had before this patch series, locally 
modify them to pass -fopenmp-simd and make sure they fail the same way 
before and after this patch.
