Most of these tests check the specific structure of lambdas when they
are generated as classes, and they start to fail once invokedynamic
lambdas are enabled by default.
Ensure that when .entries is accessed from an inline function body
or lambda argument, EntriesMapping are properly generated and used
without excessive mappings and duplicated fields

E.g. in `x + f()` where `f` is an inline lambda, the instructions for
`+` should have the line number of that expression (while previously
they instead had the line number of the last line of the lambda).
^KT-51738 Fixed
We are going to deprecate `WITH_RUNTIME` directive. The main reason
behind this change is that `WITH_STDLIB` directive better describes
its meaning, specifically it will add kotlin stdlib to test's classpath.
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.

This commit fixes the following tests:
- KotlinSteppingTestGenerated.StepOver#testSoInlineLibFun
- KotlinSteppingTestGenerated.StepOver#testSoInlineIterableFun
- KotlinSteppingTestGenerated.StepOver#testSoInlineFunOnOneLineFor
This method was introduced in c204e8fc67 "just in case" and was never
used. Therefore we're free to change its semantics and use it in all new
generated code (with API version >= 1.4), without even worrying that the
newly used API will leak from inline functions in stdlib when used with
an older API version. Since we agreed to change the type of thrown
exceptions to java.lang.NPE in KT-22275, invoke a new method
throwJavaNpe now which throws that exception instead of KNPE.
Note that the additional method that takes an exception message is still
unused and exists just in case we need to use it in the future. The new
method throwJavaNpe is public also "just in case" we need to invoke it
in the future; currently it's not invoked from the bytecode.
#KT-22275 In Progress
Dex ignores subsequent line numbers for same instructions and interprets
instruction after inline as if they were inlined. This makes debugger
behaves as if there's nowhere to stop on line with breakpoint.
This also makes stepping through inline function consistent with
non-inline analog. In both context debugger now stops on '}'.
#KT-18949 Fixed
#KT-17120 Fixed
- Turn some const conditions into non-const conditions
- Make sure inlined const values are used where required
(otherwise they are eliminated by POP backward propagation)
Finnaly markers are used only for non-local return processing and are removed after inlining to non-inline functions, same deletion should be performed on inlining to anonymous objects
#KT-16532 Fixed
Remove redundant NOPs during bytecode optimization.
NOP instruction is required iff one of the following is true:
(a) it is a first bytecode instruction in a try-catch block (JVM BE assumption);
(b) it is a sole bytecode instruction in a source code line (breakpoints on that line will not work).
All other NOP instructions can be removed.
Note that it doesn't really affect the performance for mature JVM implementations.
However, the perceived quality of the generated code is somewhat improved :).

when a method (or a property getter) returns Nothing, emit
ACONST_NULL
ATHROW
after a call so that class files verifier knows that this is an exit point in a method.
Note that if an inline method returning Nothing throws an exception explicitly
(or via a chain of inline methods), this code will be deleted by DCE.
