* fixed NoSuchMethod caused by mismatched signatures of the "invoke" method generated for lambda arguments
* added test cases in invoke.kt for KFunction and anonymous functions
* added a transformer to wrap the last expression in the bodies of lambdas with return
When a try-catch expression is passed as an argument to the inline
lambda parameter, lambda variable on stack is spilled and restored in
several different locations (1 for try-block, 1 for each catch-blocks).
So it's possible that lambda to be invoked comes from multiple loads,
all of which should have the same "root" lambda parameter.
