typed arrays: make call-as-function work for ctors

Turn call-as-function calls into constructor calls. Makes the following
snippet work:

var buf = ArrayBuffer(32);  // no 'new' but does the right thing

typed arrays: copy Buffer in typed array constructor

Convert the Buffer to an ArrayBuffer. The typed_array.buffer property
should be an ArrayBuffer to avoid confusion: a Buffer doesn't have a
byteLength property and more importantly, its slice() method works...

typed arrays: make DataView throw on non-ArrayBuffer

Make the DataView constructor throw an exception when the first
argument is not an ArrayBuffer. Follows the spec and the browsers.

buffer: fix Buffer::HasInstance() check

It was returning true for typed arrays. Check that the object was
instantiated with the Buffer constructor.

Revert "typed arrays: only share ArrayBuffer backing store"

We're going to fix this differently. The real bug is that
Buffer::HasInstance() returns true for typed arrays.

This reverts commit 01ee551e704776d8547250ac015a5463613afb45.

Revert "typed arrays: copy non-ArrayBuffer in DataView ctor"

We're going to follow browser behavior here.

This reverts commit 7b0770bff56122c245f83e8ee9608e1a0082c15e.

typed arrays: copy non-ArrayBuffer in DataView ctor

This is commit 01ee551, except for the DataView type this time.

Make the behavior of DataView consistent with that of typed arrays:
make a copy of the backing store.

typed arrays: only share ArrayBuffer backing store

Follow browser behavior, only share the backing store when it's a
ArrayBuffer. That is:

var abuf = new ArrayBuffer(32);
  var a = new Int8Array(abuf);
  var b = new Int8Array(abuf);
  a[0] = 0;
  b[0] = 1;...

typed arrays: fix DataView endianness regression

Fix an off-by-one error introduced in 9fe3734 that caused a regression
in the default endianness used for writes in DataView::setGeneric().

Fixes #4626.

typed arrays: fix 32 bit size/index overflow

Dean McNamee.

test: add typed arrays regression test

Ensure that uint8 values >= 128 are correctly promoted to int8 <= -1.

test: fix simple/test-typed-arrays

  • It incorrectly uses assert(a, b) instead of assert.equal(a, b), meaning all
    relevant assertions will pass regardless of whether they're supposed to when
    a == true.
  • It makes the assumption that elements in typed arrays for numerical types...

typed arrays: add Buffer -> TypedArray constructor

- create a typed array from a node::Buffer object
- update TypedArray::set() to spec
- add TypedArray::get() method
