Spill stack before analyzing it when looking for non-inline suspend lambda
parameters of inline function. Otherwise, it leads to AnalyzerException, when inlined lambda contains try-catch block. The reason is simple: in try block, we leave some variables on stack, while on catch block the stack is empty. Spilling the variables before try block does the trick. #KT-34708 Fixed
