`C?` can be unboxed into `T?` if if wraps a reference type `T!!`, but in
this case `null` is not a valid value to pass to `toString-impl`.
#KT-42005 Fixed
The JVM BE inlines calls to the underlying function in a $default stub
verbatim, e.g., without renaming LVT entries or regenerating anonymous
objects. This commit introduces the same behavior in the JVM IR BE.
Fixes KT-36769.
Reimplement the same hacky approach used in the old backend (see
cc2fe6b0c6).
Previously, the debugger incorrectly stepped into Collections.kt on
"step over" inline function calls from stdlib like 'any'.
Since `if` and `when` expressions are represented the same way in IR,
the behavior is fixed for both of them. It's not the case in the old JVM
backend, where stepping over `when` conditions still suffers from the
same problem, which the newly added test checks.
- Merge `duplicatingItemsSameHashCode.kt` and
`duplicatingItemsSameHashCode2.kt` into one test enabled on both
backends, and rename it to
`duplicatingItemsSameHashCodeFewBranches.kt`.
- Rename `duplicatingItemsSameHashCode3.kt` to
`duplicatingItemsSameHashCodeMoreBranches.kt`, and also enable it for
both backends.
- Use JVM_TEMPLATES/JVM_IR_TEMPLATES to check backend-specific behavior:
1) JVM IR does not optimize less than 2 branches by design
2) JVM IR does not generate duplicate branches, also by design

NB some cases such as captured extension receiver for an extension
lambda are not supported yet; to be discussed, to what extent should we
actually follow JVM code shape here.
it during spill-unspill.
Coerce int to boolean, otherwise, VerifyError is thrown on android
Completely rewrite SpilledVariableFieldTypesAnalysis... again,
but this time use BasicInterpreter
This way, the analysis both does not use SourceInterpreter and
is in line with the rest on analyses.
1. Enum entry fields don't have nullability annotations.
2. Enum class special methods (values, valueOf) are not 'final'
(although they probably should be, javac generates corresponding
methods without ACC_FINAL flag).
3. Enum class special methods don't have nullability annotations.
4. Don't generate synthetic accessor for enum entry class constructor.
