Comment update
Lift result of enum substraction when operation is lifted due to non-nullable enum type. Fixes #13454
Remove CultureInfo.CurrentCulture dependency from ordinal based string::EndsWith. Fixes #13509
Revert the use of mono_binary_search () in support/supportw.c.

This code can't depend on mono/utils and doesn't need the 'fixed'
implementation of bsearch () anyway since keys are never null.
