This is needed for the inliner: since the information about Kotlin type
of the bound receiver is nowhere in the output binary, the inliner will
have no clue how to box inline class values. Moving the boxing outside
the object means the inliner doesn't need to know about it; from its
point of view, the captured value has type `Any`.
This avoids an extra call to 'analyze', which is rather costly.
Update debugger testData: Constant condition
elimination now performs DCE more consistently.
This filters it out for use in SAM wrapper generation with
invoke-dynamic.
The intrinsic is not actually used for code generation so
it is added to the list of intrinsics that should have been
lowered away before codegen.

The previous way of getting them either via getter or setter failed on
Java properties which only have a backing field. Now that IrProperty has
overriddenSymbols (after 53c1de172f), it makes sense to use it directly
instead. Use it only in SyntheticAccessorLowering though to avoid
breaking Kotlin/Native (see KT-47019).

1. if an argument of a `pop` cannot be removed, then all other potential
arguments of that `pop` can't be removed either, and the same applies
to other `pop`s that touch them;
2. the same is true for primitive conversions, but this is even trickier
to implement correctly, so I simply did the same thing as with
boxing operators: replace the conversion itself with a `pop` and keep
the argument as-is.
Somehow this actually removes *more* redundant primitive type conversions
than the old code in a couple bytecode text tests, so I've patched them
to kind of use the value, forcing the instructions to stay.
#KT-46921 Fixed
CoroutineTransformermethodVisitor attempts to extend the ranges
of local variables in various situations. Probably in an attempt
to give a better debugging experience. However, all of these
range extensions lead to invalid local variable tables where
something is in the local variable table where nothing is in the
corresponding slot.
The code that extends variables to the next suspension point
instead of ending them when they are no longer live has issues
with loops. When resuming and reentering the loop, the locals
table will mention a local that we did not spill and which
is therefore not restored when resuming.
The code that extends local variable table entries if there
are no suspension points between two entries doesn't work
for code such as:
```
var s: String
if (suspendHere() == "OK") {
s = "OK"
} else {
s = "FAIL"
}
```
If the local variable ranges are collapsed into one, one of
the branches will have the local defined in the local variable
table before the slot is initialized.
