      Reland "Clean up macros" · 0c7b551f
      Ng Zhi An authored 
      This is a reland of 08b26f53

Fixed the original crash, by removing a disasm for psllq and psrlq
that is now handled by the macro list.

Original change's description:
> Clean up macros
>
> Move some instruction definitions into sse-instr, which is used to
> generate some disasm tests, so we can remove some cases there.

      [mips]Reland^2 "[runtime] Move Context::native_context to the map" · d8ba2856

Original Commit Message:

    This is a reland of c7c47c68.

    This makes TSAN happy in addition to:

    Previously I presumed that the context read from a frame in the profiler was
    a valid context. Turns out that on non-intel we're not guaranteed that the
    frame is properly set up. In the case we looked at, the profiler took a
    sample right before writing the frame marker indicating a builtin frame,
    causing the "context" pointer from that frame to be a bytecode array. Since
    we'll read random garbage on the stack as a possible context pointer, I made
    the code reading the native context from it a little more defensive.
