This change allows to revert adding `WITH_STDLIB` directive
to tests which happened at `a9343aeb`.

This inconsistency is present due to not using the `// WITH_STDLIB`
in the above tests. When K1 creates the enum, it tries to generate
`entries()`, and for that it tries to load `kotlin.enums.EnumEntries`,
but this is actually an unresolved reference. K1 silently swallows it,
and proceeds.
The reason K2 doesn't fail is that in order to generate `entries()` it
simply creates the necessary `ConeClassLikeType` with the desired
`classId` instead of loading the whole `ClassDescriptor`.
The reason we can still observe `$ENTRIES` and `$entries` in K1
is because they are generated during the JVM codegen, and it
only checks if the `EnumEntries` language feature is supported. It
doesn't check if the `entries` property has really existed in IR
(by this time it's expected to have already been lowered to the
`get-entries` function - that's why "has ... existed").
The reason why the codegen doesn't fail when working with
`kotlin.enums.EnumEntries` is because it creates its
own `IrClassSymbol`.

- Use typed Wasm tables for each interface method to avoid runtime
function type check
- Use linear search by implemented interface rather than by individual
virtual function signature
Now FE IR -> BE IR transformation is performed in multiple stages
controller by Fir2IrConverter. Stages are
* files & classes registration
* supertypes & type parameters handling
* functions & properties signature generation
* body generation
After each step we have guarantee (with exception of local classes &
type inference combination, and external symbols) that required symbols
(class/function/property/variable/type parameter)
are already bound to real declarations and have correct parents.
This commit also fixes incorrect parents for local classes
IR expects overridden symbols of "invoke" in KFunction to be "invoke"
in the corresponding Function classes.
Before this commit we don't set overriddenSymbol, now we do.
In TopDownAnalyzerFacadeForJVM, we now always use the "load built-ins
from module dependencies" behavior that was previously only enabled with
the dedicated CLI argument -Xload-builtins-from-dependencies. However,
sometimes we compile code without kotlin-stdlib in the classpath, and we
don't want everything to crash because some standard type like
kotlin.Unit hasn't been found.
To mitigate this, we add another module at the end of the dependencies
list, namely a "fallback built-ins" module. This module loads all
built-in declarations from the compiler's class loader, as was done by
default previously. This prevents the compiler from crashing if any
built-in declaration is not found, but compiling the code against
built-ins found in the compiler is still discouraged, so we report an
error if anything is resolved to a declaration from this module, via a
new checker MissingBuiltInDeclarationChecker.
Also introduce a new CLI argument -Xsuppress-missing-builtins-error
specifically to suppress this error and to allow compiling code against
compiler's own built-ins.
#KT-19227 Fixed
#KT-28198 Fixed
This however makes testLocalFunctionName fail because currently
isSubclassOf (incorrectly) returns false and therefore an anonymous
class is generated and the name is taken from there. The name there is
"box$OK" which is incorrect. The isSubclassOf issue is KT-28198 and will
be fixed separately; the incorrect name issue will be investigated later
Anonymous classes for local function references implement their
getOwner() as "return null" currently (KT-14291). To avoid NPE in this
case, we now consider two local functions the same if their name and
signature are equal. This is incorrect in general, but unlikely to cause
major problems and is going to be fixed by KT-14291 eventually anyway
