Reland "Improve support for arrays in Metal." This reverts commit 38df4c8470ab3db7455005ab0c3599a95c791d2b. Reason for revert: updated ArrayTypes test for ES2 compatibility Original change's description: > Revert "Improve support for arrays in Metal." > > This reverts commit dd904af5666b4746d4b9af5c1f03b47ac3ec73b2. > > Reason for revert: breaks ANGLE > > Original change's description: > > Improve support for arrays in Metal. > > > > Arrays in Metal now use the `array<T, N>` type instead of the C-style > > `T[N]` type.
