Based on instrumentation 0.2% of all
mono_gc_wbarrier_value_copy_internalcalls in a run of System.Runtime.Tests are fromMINT_STELEM_VT. I suspect adding this NOREF version of the opcode will improve performance for data structures that store structs in arrays but don't contain any references - for exampleList<ValueTuple<...>>orDictionary<int, int>- but it's hard to measure locally.
