71678b4bdf IRGen/Runtime: Expose the 'isBitwiseTakable' bit in the value witness flags. 
Set a bit for types that are non-bitwise-takable, and calculate it as part of runtime struct and enum layout. Include 'bitwise takable' as part of the runtime 'is inline' calculation to be consistent with the compile-time policy change in r17008.

3e0c1cebcf Runtime: Update the 'inline storage' flag properly for single-payload enums. 
It cannot be simply inherited from the payload value witness table; it needs to be recalculated for the new type's size.
