decompiling lambdas fails due to missing local variable declarations

[jurgenvinju]

This is a disassembled lambda where you can see that there are no LOCALVARIABLE instructions for stack location 0 and 1. This stops their LOAD instructions from being decompiled and that blocks further decompilation steps downstream.

My guess is that the creating scope is captured by the 0 and 1 stack locations in lambda's, and so we need to add rules for recovering expressions for these LOADs somehow.
