1. - *.y: fixed context inside lambda args and module. …

   Previously we didn't push a context for module and lambda arguments and so we didn't reject some code.
   However, examples that should've raised errors are complicated and it's very unlikely that any code was affected.
   
   Examples of code that is accepted/rejected differently after this change:
   1. ->(a) { module M; _1; end }
   We didn't push context for module M, and so argument `a` conflicted with implicit parameter `_1`.
   
   2. class A; ->(a = (return; 1)) {}; end
   This code is valid, because `return` is a part of the lambda. But we didn't store this fact internally, and so it was rejected before.
   
   Both examples described above (and all similar variations) are fixed in this commit.
