Add comment for the forked Dart revision for the assembler code.

Also note to keep that up to date. See also Patch set 1 of https://codereview.chromium.org/574133002/, vs later patch sets. Some things that were changed: (*) Headers / constants use Ice version (RegX8632::Encoded_Reg_eax vs EAX), (KB / MB -> other...) (*) Use llvm/Subzero allocator instead of Dart one. (*) Class/Field/On-stack-replacement/Dart runtime stuff is removed (*) Relocation/Fixups are now POD -- rather than a class with a virtual method for fixup. For now, we write out an ELF relocation, but later we may do a target pass to handle function calls within the same section, etc. (*) ASSERT -> assert (*) uword -> uintptr_t (should check). (*) clang-format (*) ??? BUG=none R=stichnot@chromium.org Review URL: https://codereview.chromium.org/901453002
