d208eea478 Speed-up 'new TypedArray(arrayLike)'. 
Handle specially the cases when the argument is a typed array,
in particular of the same type as the one we create.

Allocate backing store uninitialized in cases when we can guarantee
complete initialization.

a4c072ed47 Fix a crash when generating forward jumps to labels at very high assembly offsets 
The first jump to a specific label was marked as jump to absolute
position -4. This value was stored in the assembly as a branch to a
offset (-4 - (instruction offset + 8)). The offset is only 24 bit
long on ARM. Thus instruction offsets higher than 2^23 - 12 would overflow
the offset.

Fix by denoting the first jump to a label by storing the jump
instruction location as the target. This will result in offset of -8,
which of course always fits in the branch instruction.

e53471dbaa Remove elements transitions from the transition array. 
This is preparatory work for reordering the transition tree. Since elements transitions will be at the root of the transition tree, runtime access to them is slow since we have to walk the transition tree backwards first. Hence remove the optimization that promoted them to a special field, requiring a pointer (mostly NULL) in every non-simple transition array.

3143f5f88b Remove special handling of fields in combination with elements transitions in Crankshaft. 
Instead first try to keep ICs monomorphic if elements kinds generalize. If that fails, use standard polymorphic handling. The Try*PolymorphicAsMonomorphic methods will automatically produce code similar to the previous approach using CheckMapsWithTransitions.

bacc626f57 Fix HType handling for HConstant with external references. 
We cannot use set_type() with HType::None() in the HConstant
constructor, since set_type() asserts that the new type is a
subtype of the previous one, but HType::None() is not a subtype
of HType::Tagged() which is the initial type set by the HValue
constructor.

This patch adds an optional type parameter to the HValue,
HInstruction and HTemplateInstruction constructors.

In order to properly sanitize exception data during a 'window.onerror'

headers at the time it was loaded into V8. This patch adds a single bool
to ScriptOrigin, and pipes that through the compiler to land on the
Script object. We can then retrieve the parameter when calling the
embedder's exception callback.

using a loop and a worklist instead, to avoid potential stack
overflows.

4b35b76509 Adapt test expectations for blink test. 
Also after giving it more time, this test times out only on the V8 waterfall under windows. It has an existing expectation for Win Debug, which holds now for all Win.

6475cb4d95 Repair test expectations for webkit test. 
When adding the new tests in https://codereview.chromium.org/21070002/ the tabs in .js files were automatically replaced with spaces (for presubmit to work).

This replaces the tabs also in a test expectation file for the output to match again.
