      [wasm-simd][liftoff][ia32] Fix operands on non-AVX · 236aff1b
      Zhi An Ng authored 
      The main fix here is on non-AVX builds, the shifts require dst == src.
Calling macro-assembler functions like Psrlw assumes that we already
met that requirement (which we usually specify in TurboFan's
instruction-selector). On Liftoff, we need to do that check manually.
This is done by using the helper EmitSimdShiftOpImm which will do this
check, and dispatches to AVX if supported, or mov if dst != src.

Also fix a couple of places where we forgot to annotate the required SSE
extension for the instruction.

      [wasm-simd][x64] Don't fix dst to src on AVX · d4f7ea80
      Zhi An Ng authored 
      On AVX, many instructions can have 3 operands, unlike SSE which only has
2. So on SSE we use DefineSameAsFirst on the dst. But on AVX, using that
will cause some unnecessary moves.

This change moves a bunch of instructions that have single instruction
codegen into a macro list which supports the this non-restricted AVX
codegen.

      [map] Try to in-place transition during map update · 8e3ae62d
      Leszek Swirski authored 
      When searching for a target map during map update, attempt to
update field representations in-place to the more general
representation, where possible.

      [tools][system-analyzer] Improve timeline track · 95e1fa50
      Camillo Bruni authored 
      - Use initial color for TimelineTrack chunks
- Use async functions for TimelineTrack setChunkBackgrounds
- Introduce timeSelection setter on TimelinePanel
- Propagate time selection down to the TimelinePanel
- Avoid layout recalculation in TimelineTrack updateSelection

drive-by-cleanups:
- Add common event listeners only to top-level document
- Use console.warn instead of console.error for better debugging in
  DevTools
