Traverse multiple store-load chains for inlined lambda parameters

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.
