X87: [builtins] Always pass target and new target to C++ builtins.

  port f5b83dec (r37061)

  original commit message:
  As a first step towards showing builtin frames in stack traces, we will now
  push target and new target unconditionally.

  Since the various specializations of BuiltinArguments are made redundant by
  this change, we can remove them and all related code.
