Fix verify error with 'return when/if/try' in suspend function

Browse Source 
The problem appears for tail-optimized suspend functions,
we erroneously assumed that when/if/try expressions in tail-call
position have simple types like `I` while actually, they can return SUSPENDED
object, i.e. must have `java/lang/Object` as return type.

But this only concerns branching operations in tail-call position,
so we have to make an additional analysis for remembering whether
a given expression is in a tail-call position.

Also, it's important here that we now assume
the return type of the current function  as `java/lang/Object`
that is necessary to avoid wrong checkcasts.
