Lifts try's that might be executed on non-empty expression stacks to their own methods. I.e.
try body catch handler
is lifted to
{ def liftedTree$n() = try body catch handler; liftedTree$n() }
However, don't lift try's without catch expressions (try-finally).
Lifting is needed only for try-catch expressions that are evaluated in a context
where the stack might not be empty. finally does not attempt to continue evaluation
after an exception, so the fact that values on the stack are 'lost' does not matter
(copied from https://github.com/scala/scala/pull/922).

Is this phase the standard typerphase? True for TyperPhase, but not for other first phases (such as FromTasty or Parser). The predicate is tested in some places that perform checks and corrections. It's different from ctx.isAfterTyper (and cheaper to test).
