18a6bde156 Kotlin: converge delegated-property accessor body expression locations onto the delegate expression
The synthesised body of a delegated-property accessor (`get`/`getValue`/
`setValue`/`invoke` calls, the `<prop>$delegate` access, associated type
accesses and property-reference classes) carries the source range of the
whole `KtPropertyDelegate` node. The K1 frontend's range starts at the
`by` keyword; K2 starts at the delegate expression itself
(e.g. `lazy { ... }`), three columns later. The `by` keyword is syntactic
glue in the property declaration, not part of the expression being
evaluated, so K2's narrower range is the more intuitive one. Adopt it for
both frontends. Example:

  get / getValue / invoke ...  6:24:9:9  ->  6:27:9:9

Add a scoped offset remap on `FileTrapWriter`: while extracting a
`DELEGATED_PROPERTY_ACCESSOR` body, any location whose offsets exactly
equal the `by`-inclusive delegate range is emitted with the delegate
expression's range instead. The range is recovered from the enclosing
`KtProperty`'s PSI (`delegate.expression`), which is available under K1;
under K2 there is no PSI so the remap is inactive and the raw offsets
already exclude `by`. Matching the full delegate range exactly means only
these synthesised body expressions are affected.

Updates test-kotlin1 expected only (test-kotlin2 unchanged).

b2f94da372 Kotlin: converge delegated property accessor locations onto K2 property span
For local and member delegated properties, the synthesised accessor
(`<get-prop>`/`<set-prop>`) and its generated wrapper class/constructor
were anchored by the K1 frontend at the delegate expression rather than
at the property declaration. K2 (raw IR) anchors them at the property
`val`/`var` keyword through the end of the delegate, i.e. the whole
`KtProperty` span.

Adopt the K2 span for both frontends so the extractor emits identical
locations regardless of the supplied language version. Example:

  <get-prop1>  6:24:9:9  ->  6:9:9:9

Add `getPsiBasedDelegatedAccessorLocation`, which walks from the
accessor's PSI up to the enclosing `KtProperty` and returns its span.
It returns null when there is no PSI (K2) or no enclosing property, so
K2 keeps its native locations and non-delegated callables are
unaffected. Wire it into `extractFunction`'s location chain and into
`extractGeneratedClass` (guarded on `DELEGATED_PROPERTY_ACCESSOR`) so the
generated class/constructor sorts before the method, matching K2.

Updates test-kotlin1 expected only (test-kotlin2 unchanged).

e37d89b849 Kotlin: converge default property-accessor locations onto the K2-native spans
Synthesised and bare `get`/`set` accessors were extracted with different
source locations depending on the frontend:

    val typedProp: Int = 3            // getTypedProp
        K1: 5:5:5:17  (val..name)     K2: 5:5:5:22  (val..type)

    val defaultGetter = 7
        get                           // getDefaultGetter
        K1: 19:5:19:21 (property head) K2: 20:13:20:15 (`get` keyword)

Under K2 the extractor has no PSI back-mapping for these accessors
(`getKtFile` returns null), so it cannot reproduce K1's property-name-end
span; K2 instead falls back to the raw IR offsets. Rather than converge on a
value K2 cannot produce, K1 is made to match the K2-native spans via the PSI:

  * a bare `get`/`set` keyword now points at the keyword token; and
  * a fully synthesised accessor now spans the property signature
    (`val`/`var` .. type annotation, or .. name when untyped), excluding the
    initialiser.

Explicit-body accessors (`get() = 5`) are unaffected: they are located at
their body and never take this override.

Only K1 output changes; the test-kotlin2 (K2) expected files are unchanged.

7eb71807cd fix property and accessor locations using PSI
K1 IrProperty.startOffset includes leading modifiers (private, abstract,
lateinit, annotations) in the span start; K2 already starts at val/var.
Walk the PSI tree from p.startOffset to the enclosing KtProperty, then use
valOrVarKeyword.startOffset as the declaration start, giving a consistent
start in both K1 and K2.

Two related but distinct locations are derived from the KtProperty:

- The property itself spans val/var through the end of the full
  declaration (KtProperty.endOffset), including an explicit getter/setter
  body on a following line. This is getPsiBasedLocation(IrProperty).
- Synthesised accessors (DEFAULT_PROPERTY_ACCESSOR origin) span val/var
  through the end of the property name (KtProperty.nameIdentifier.endOffset)
  via getPsiBasedAccessorLocation, applied through accessorOverride().
  Explicit getter/setter bodies keep their own independently computed
  location.

This makes K1 accessor locations match K2 and gives each synthesised
accessor a precise span, rather than the property's full declaration span.

Example (properties.kt line 3, "var modifiableInt = 1"):
  property  modifiableInt     -> 3:5:3:25   (val/var .. end of "= 1")
  accessor  getModifiableInt  -> 3:5:3:21   (val/var .. end of name)
  accessor  setModifiableInt  -> 3:5:3:21

Because accessor locations appear wherever accessors are reported, this
refinement updates many expected files (property listings, modifiers,
methods, reflection, control-flow and expression dumps). Every change is a
location-coordinate change only: no result tuple is added or removed.

The PSI-based location is restricted to unspecialised extractions
(classTypeArgsIncludingOuterClasses.isNullOrEmpty()). Specialised generic
instances (e.g. C<String>.prop) continue to use the binary whole-file
location returned by getLocation(p, typeArgs), preserving the existing
behaviour that keeps them absent from fromSource() queries.

The visibility merge in extractFunction is extended to accept an
overriddenAttributes parameter from the caller; the internal fake-override
visibility adjustment (DescriptorVisibilities.PUBLIC for Java binary Object
methods) is merged with any caller-supplied attributes so that neither
overrides the other silently.
