Alexander Markov 5b6512f54e [vm/aot] Disable signature shaking for 'this' of inline class members 
Specification of inline classes has the following rule for
closurization (tear-off creation) of inline class members:

> The operator == of the closurization returns true if and only if
> the operand is the same object.

This means that each time tear-off is taken, a new closure should be
created which compares equal only to itself. This is true iff that
closure has a non-empty context which captures 'this'.

Signature shaking can remove 'this' parameter if it is not used
and this affects equality of the tear-offs of inline class members.
This change prevents that by marking 'this' parameter of inline
class members as checked.
