The patch adopts and reuses the optimizations from the legacy backend. The optimizations remove useless temporary variables, statements and simplify generated JS code. The optimizations can be disabled by `-Xoptimize-generated-js=false`. Related to KT-51139

// JVM_IR uses the line number of the start of the `when` as the line number
|
|
// for the lookup/table switch. Therefore when the subject and the when is
|
|
// on separate lines the first step is on the subject, then steop to the when,
|
|
// then to the right branch.
|
|
|
|
// JVM_IR uses optimized lookup/table switches for all these cases. JVM
|
|
// does not. So on JVM there are steps on each condition evaluation for
|
|
// the first `when`.
