      Description

      Changes:
      - Removed all array storage properties related code
      - Now using array tags in layout helper to determine flattened/null-free properties
      - Removed handling of inline/indirect mirror
      - Removed _asPrimaryType/_asIndirectType intrinsics and removed usages of corresponding API from tests
      - Refactored loop unswitching code and added more tests
      - Removed all special casing in the typesystem that was necessary to support [V <: [V? with the klass for [V not being equal to the klass for [V?

      The code that clears the property bits when loading the klass pointer from the metadata is still in but marked with: "// TODO remove clear_prop_bits bits stuff once the runtime does not set it anymore"
