Message:
PTAL
Description:
Remove special handling of fields in combination with elements transitions
in
Crankshaft.
Instead first try to keep ICs monomorphic if elements kinds generalize. If
that
fails, use standard polymorphic handling. The Try*PolymorphicAsMonomorphic
methods will automatically produce code similar to the previous approach
using
CheckMapsWithTransitions.
