The hash is not really mapping the simd DECL to the simduid, since that's just
a matter of DECL_UID(simduid), but the OMP simd array to the index used to
reference it (simduid), like thus:

         _7 = GOMP_SIMD_LANE (simduid.0)
         ...
         ...
         D.1737[_7] = stuff;

decl_to_simduid is a mapping from the simduid.0 to the D.1737[] (the OMP simd
array).

Agreed, or am I missing something?


Agreed.  Yeah, that's a bit confusing.


Ok, I will change the hash name and add some comments.
