Unlike previously, this optimisation works on every callee return type.
Tail-calls inside unit functions can be either
INVOKE...
ARETURN
or
INVOKE
POP
GETSTATIC kotlin/Unit.INSTANCE
ARETURN
The first pattern is already covered. The second one is a bit tricky,
since we cannot just assume than the function is tail-call, we also need
to check whether the callee returned COROUTINE_SUSPENDED marker.
Thus, resulting bytecode of function's 'epilogue' look like
DUP
INVOKESTATIC getCOROUTINE_SUSPENDED
IF_ACMPNE LN
ARETURN
LN:
POP

coroutines intrinsic lambda.
The logic is if the lambda is crossinline we need to generate the
accessor. However, suspendCoroutine's and
suspendCoroutineUninterceptedOrReturn's parameter, despite being
crossinline, are effectively inline. Thus, we do not need to generate
the accessor.

This is possible now because after 3a9b94235f, 0423d0f41e and
5341de253f, all top level functions/properties in sources and in
binaries have a corresponding containing facade class
This is actually either a LAMBDA or an ANONYMOUS_FUNCTION.
Not quite sure if it's really required, but some tools such as IR-based
decompiler might require this information.
last-exclusive progressions (i.e., "until" progressions and loop over
array indices).
This change makes it possible to correctly implement the handling of
"step" progressions. Computing the last element of a stepped progression
requires that the last is inclusive.
Also invert the while loop (into if + do-while) that is used when
lowering for-loops over progressions that cannot overflow. This keeps
the performance characteristics closer to the ForLoopsLowering in
kotlin-native, since the goal is to converge to this shared version.
Also used IrType instead of KotlinType, where possible.

Unfortunately this cannot currently be done for the extension overload which accepts a radix due to behavior difference with regard to invalid radix values.
This fixes an issue in constructing annotation instances with array
class elements. For some reason, behavior of `ClassLoader.loadClass`
differs from `Class.forName` in handling arrays, namely:
* `loadClass("[Ltest.Foo;")` returns null
* `Class.forName("[Ltest.Foo;")` returns class for array of test.Foo
Overall, there doesn't seem to be any way to load an array class with
`CLassLoader.loadClass`.
We pass initialize=false to forName because this is the behavior of
ClassLoader.loadClass: it doesn't perform class initialization (e.g.
<clinit> is not executed).

Context for determine if a value parameter is captured from outer
context is not directly available after lowering, hence introduce a new
IrDeclarationOrigin for captured receiver parameter to avoid duplicate
calculation.
