It allows using NonNMethod code space for method handle intrinsics which are needed urgently if the other code cache spaces are full. There are other options (see JBS issue), but this one appears to be the simplest one.

I think we need a test for this case, even if it requires the use of WhiteBox to trigger it reliably.  For an alternative solution, can't we fall back to using the pre-generated interpreter entries?
