The proper support will come in KT-15518, but that would be a breaking
change even for stable Kotlin without kotlin-reflect. Before that issue
is fixed, represent Nothing in types with the Void class, and use a flag
in the no-reflect implementation to remember that it's not actually the
Void class itself.

Otherwise an invalid type is constructed which causes kotlin-reflect to
crash, and stdlib implementation to render the type incorrectly. The
reason is that suspend functional types are not properly supported in
reflection. Once they are supported, this error can be removed.

Crossinline lambdas *can* be inlined into objects, but don't *have* to;
the correct place should be determined from the context, not from the
parameter.
Printing the call site source on errors isn't really useful anyway - the
old backend points to a specific PsiElement, and JVM_IR wraps the
exception in FunctionCodegen (and printing the source never worked with
JVM_IR anyway).
rather than a fake inline function.
Also, generate more correct instructions for typeOf. Not sure how that
even worked before - `aconst(Boolean)` isn't even valid.
This avoids an extra call to 'analyze', which is rather costly.
Update debugger testData: Constant condition
elimination now performs DCE more consistently.
To avoid depending on a heavy module 'frontend' in parts of the compiler
where checking for optional annotations is needed, such as in
'ir.serialization.common'.
Anonymous types are not approximated by frontend for private declarations.
Class IDs for such types are replaced by StringTable before being written
to metadata. JVM string table mangles such types and keeps them generic
for reflection. For other purposes the types are replaced with `Any`.
Type arguments of the replaced type should be ignored in the latter case.
Otherwise decompiled text builder crashes on an attempt to restore `Any`
type with non-zero number of type arguments.
The code pretending to replace a type with its first supertype was dropped
from ApproximatingStringTable for two reasons:
- the first type from `getAllSuperClassifiers` is the original type itself
which doens't provide a ClassId for anonymous type, so it was a noop
- tracking potential type arguments of the first anonymous type's supertype
would be a complication with almost no practical value (types in decompiled
text would be slightly closer to the real type of a private declaration).

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.
