      [interpreter] Add support for scalable operands. · 48d082af
      oth authored
      This change introduces wide prefix bytecodes to support wide (16-bit)
      and extra-wide (32-bit) operands. It retires the previous
      wide-bytecodes and reduces the number of operand types.
      
      Operands are now either scalable or fixed size. Scalable operands
      increase in width when a bytecode is prefixed with wide or extra-wide.
      
      The bytecode handler table is extended to 256*3 entries. The
      first 256 entries are used for bytecodes with 8-bit operands,
      the second 256 entries are used for bytecodes with operands that
      scale to 16-bits, and the third group of 256 entries are used for
      bytecodes with operands that scale to 32-bits.

      [Interpreter] Make InterpreterAssembler a subclass of CodeStubAssembler. · d1c28849
      rmcilroy authored
      Moves InterpreterAssembler out of the compiler directory and into the
      interpreter directory. Makes InterpreterAssembler as subclass of
      CodeStubAssembler.
      
      As part of this change, the special bytecode dispatch linkage type
      is removed and instead we use a InterfaceDispatchDescriptor and
      a normal CodeStub linkage type.
      
      Removes a bunch of duplicated logic in InterpreterAssembler and
      instead uses the CodeStubAssembler logic. Refactors Interpreter
      with these changes.
      
      Modifies CodeStubAssembler to add the extra operations required
      by the Interpreter (extra call types, raw memory access and some extra
      binary ops). Also adds the ability for subclasses to add extra
      prologue and epilogue operations around calls, which is required
      for the Interpreter.
