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.
The variable generated by IrStatementBuilder.irTemporary doesn't inherit
startOffset and endOffset from the builder. In particular, as a result,
temporary variables generated for elvis operator left operand have
UNDEFINED_OFFSET.
Additionally, ProvisionalFunctionExpressionLowering copies the offsets
of a variable to lowered lambda in the variable initializer. With the
problem described above, this causes invalid debug information in
Kotlin/Native, see KT-49360.
Fix irTemporary by using builder's offsets for the variable.

Descriptors are already supposed to be sorted in scopes. The problem is
that rendering descriptors for sorting takes a lot of time (~1.5% of
total compilation time of intellij with JVM IR), and simple heuristics,
like comparing by names first, don't fully help with it.

- Access underlying fields directly, instead of using accessors. This is
safe since data classes are always final.
- Don't generate a temporary variable in hashCode to use as the
accumulator.
Both optimizations are effectively present in the current JVM backend
and with these changes the generated code is much closer to what the
current backend generates.
They are currently marked as defined even when they get a
default implementation. That makes it hard to figure out
if the accessor should be removed when introducing a backing
field in the JVM_IR backend.
