SC: set groovy property written for variable expression assignment that should be direct setter call

Consider the following:

class A {
  void setX(Date value) {}
  void setX(Long value) {}
}
class B extends A {
  void m() {
    x = 42L
    x = new Date()
  }
}

When compiled with @compileStatic the method "m" contains calls to ScriptBytecodeAdapter.setGroovyObjectProperty for the assignment statements. If "x" is replaced by "this.x" direct setter calls are written instead, as expected.
