RFR: 8261956: [type-restrictions] Support RestrictedMethod in the interpreter

[Frederic Parain]

Please review these changes adding support for RestrictedMethod in the interpreter.
Types restrictions are enforced in the following bytecodes:
  - invokevirtual
  - invokestatic
  - invokespecial
  - invokeinterface
  
The changeset also includes a small fix to prevent previous type restrictions related tests to fail.

Thank you,

Fred
