      [WASM SIMD] Implement primitive shuffles. · 5806d862
      bbudge authored 
      - Adds unary Reverse shuffles (swizzles): S32x2Reverse, S16x4Reverse,
  S16x2Reverse, S8x8Reverse, S8x4Reverse, S8x2Reverse. Reversals are
  done within the sub-vectors that prefix the opcode name, e.g. S8x2
  reverses the 8 consecutive pairs in an S8x16 vector.

- Adds binary Zip (interleave) left and right half-shuffles to return a
  single vector: S32x4ZipLeft, S32x4ZipRightS16x8ZipLeft, S16x8ZipRight,
  S8x16ZipLeft, S8x16ZipRight.

- Adds binary Unzip (de-interleave) left and right half shuffles to return
  a single vector: S32x4UnzipLeft, S32x4UnzipRight, S16x8UnzipLeft,
  S16x8UnzipRight, S8x16UnzipLeft, S8x16UnzipRight.

- Adds binary Transpose left and right half shuffles to return
  a single vector: S32x4TransposeLeft, S32x4TransposeRight,
  S16x8TransposeLeft, S16xTransposeRight, S8x16TransposeLeft,
  S8x16TransposeRight.

- Adds binary Concat (concatenate) byte shuffle: S8x16Concat #bytes to
  paste two vectors together.

      Remove "calls eval" bit from ParseInfo and PreParseData · 9b512732
      Adam Klein authored 
      There's no reason to keep track, for a preparsed function itself,
whether that function calls eval. All that matters is that the ancestor
scopes are marked as having an inner scope which calls eval. The function
will have its "calls eval" bit persisted if/when it's fully parsed.

The only "behavioral" change in this patch is the removal of a DCHECK.

      [parser] avoid complex for-loop desugaring when possible · 267115da
      Caitlin Potter authored 
      let/const declarations in "standard" C-style for-loops have
some complex desugaring to accommodate the case where loop
loop variables may be captured. This slows down the baseline
performance of for-loops with let variables.

This change attempts to avoid this desugaring if it's known that
the loop variable is not captured at any point. A side effect of
this change is that let/const loop variables, when not captured
within the loop body, are not necessarily shown in the debugger,
similar to other stack-allocated vars.

      [cleanup] Remove runtime.js, move the remainder to more logical places · 468ddfa6
      Adam Klein authored 
      This patch retires runtime.js:
  - Removes some dead code from runtime.js (ToPositiveInteger, ToIndex),
  - Moves Array.prototype initialization to prologue.js
  - Moves SpeciesConstructor to the only file that calls it (typedarray.js)
  - Renames the remainder to reflect its only inhabitants ({Max,Min}Simple)

      [modules] Allow resolve-callback to signal failure. · 486cd04f
      neis authored 
      When asked for a module that previously failed to compile or
instantiate, the embedder necessarily has to signal failure.  In this
case, we expect an exception to be scheduled, which we will rethrow.
