f07b21337b MIPS: Add isolate accessor to AccessorInfo and Arguments. 
Port r11306 (36b58f7).

Original commit message:

This passes the isolate through to API callback functions so that it is
available through AccessorInfo and Arguments. This allows bindings to
avoid unnecessary TLS lookups to retrieve the current isolate.

037785baaa MIPS: Improve performance of keyed loads/stores which have a HeapNumber index. 
Port r11282 (bd2ab07).

Patch by Daniel Kalmar.

Original commit message:

Some GWT compiled code results in array access that has a heap number (e.g. -0)
as an index. Until now this would result in a generic IC.

For example:

a[-0] === a[0] or

a[0.25 * 4] === a[1]

This change detects heap numbers that are representable as a smi
and converts them. As a result we can still use the fast keyed monomorphic
ICs. Optimized code already handles keyed access with a double-key efficiently.

As a result the frame rate on the reported benchmark improves by roughly 2x.

436098b4a2 Prepare DefinePropertyAccessor for callback transitions. 
Although things are currently OK here, in the future it won't be enough to check
for the existence of a CALLBACKS result, we must additionally check that it
actually contains an accessor. In a nutshell: 'sed s/IsFound/IsProperty/' once
again...

Additionally, the control flow in DefinePropertyAccessor has been simplified by
using a helper function.

18a24a5882 MIPS: Increase external array allocation header size to 8 bytes. 
This fixes alignment issues on MIPS HW, found for example in mjsunit external-array.
The issue originates from r11144 (86563c3e21) which adds a 4-byte header to these arrays.
This causes problems on MIPS, where certain pointers need to be 8-byte aligned.

82cde7c832 Remove write-barriers for stores to new-space objects. 
This change allows hydrogen instructions to keep track of instructions
that dominate certain side-effects (GVN flags) in the hydrogen graph. We
use the GVN pass to keep track of side-effects because accurate flags
are already in place.

It also adds a new side-effect (kChangesNewSpacePromotion) indicating
whether an instruction can cause a GC and have objects be promoted to
old-space. An object allocated in new-space is sure to stay on paths not
having said side-effect.
