Fix reification for crossinline lambdas inlined into object literal

Inline lambda could capture reified parameter of containing inline function ('a' function)
when it is inlined in another one.
If it's inlined in any anonymous object we should track it and
add reification marker to such anonymous object instance creation
to rewrite it on inlining bytecode of 'a' function.
