      SIMD.js Add the other SIMD Phase 1 types. · 7b9670b6
      bbudge authored 
      Adds Int32x4, Bool32x4, Int16x8, Bool16x8, Int8x16, Bool8x16.
Adds Simd128Value base heap object class.
Changes heap/factory construction pattern to use arrays.
Adds replaceLane functions to facilitate testing.

NOPRESUBMIT=true
(presubmit checks erroneously interpret array declaration in macro definition as variable size array.)

      Expose SIMD.Float32x4 type to Javascript. · e5ed3bee
      bbudge authored 
      This CL exposes the constructor function, defines type related
information, and implements value type semantics.
It also refactors test/mjsunit/samevalue.js to test SameValue and SameValueZero.

TEST=test/mjsunit/harmony/simd.js, test/cctest/test-simd.cc

      Revert of Steps towards unification of number bitset and range types. (patchset #4 id:60001 of https://codereview.chromium.org/837723006/)

Reason for revert:
Breaks test-types/Maybe, i.e.

out/Release/cctest --random-seed=-707413401 test-types/Maybe

started failing afterwards

Original issue's description:
> Steps towards unification of number bitset and range types.
>
> - New invariant on union types: if the union has a range then the number
>   bits in the bitset must be cleared.
>
> - Various tweaks in intersection and union to satisfy the invariant.
>
> - Exposed and used representation bits in range types (and the Limits
>   helper class).
>
> - Implemented Glb for ranges so that the Is predicate handles
>   ranges correctly.
>
> - Change typer weakening so that it does not rely on GetRange.
>   However, the code still seems to be a bit fragile.
>
> - Removed the Smi types from the type system core, instead introduced
>   Signed31, Unsigned30 and created constructors for Small(Un)Signed
>   that point to the right type for the architecture.
>
> - Punched a hole in the config to be able to get to the isolate so
>   that it is possible to allocate heap numbers for newly created
>   ranges.

      - New invariant on union types: if the union has a range then the number
  bits in the bitset must be cleared.

- Various tweaks in intersection and union to satisfy the invariant.

- Exposed and used representation bits in range types (and the Limits
  helper class).

- Implemented Glb for ranges so that the Is predicate handles
  ranges correctly.

- Change typer weakening so that it does not rely on GetRange.
  However, the code still seems to be a bit fragile.

- Removed the Smi types from the type system core, instead introduced
  Signed31, Unsigned30 and created constructors for Small(Un)Signed
  that point to the right type for the architecture.

- Punched a hole in the config to be able to get to the isolate so
  that it is possible to allocate heap numbers for newly created
  ranges.

      Use std::numeric_limits<double>::quiet_NaN() and
std::numeric_limits<float>::quiet_NaN() instead.
