Patch to enhance the source code line information for profiler.
...
This patch is to enhance the source code line information for profiler.
For the Hydrogen compilation, most of the source code line information
is not copied from the HInstruction the to corresponding LInstruction.
This patch defines one PositionBits field for LInstruction and copies the
sorce code position value from the HInstruction.
When Generating the native code, we use RecordPosition(..) function to
write LInstruction's position value to position recorder.
For the MIPS platform, I did not touch because I have no devices
to verify the modification on it.

MIPS: First implementation of allocation elimination in Hydrogen.
...
Port r16098 (328ff5f7)
Original commit message:
This change implements a simple data-flow analysis pass over captured
objects to the existing escape analysis. It tracks the state of values
in the Hydrogen graph through CapturedObject marker instructions that
are used to construct an appropriate translation for the deoptimizer to
be able to materialize these objects again.
This can be considered a combination of scalar replacement of loads and
stores on captured objects and sinking of unused allocations.

Improve internal stringifcation for custom Error objects.
...
If an developer attempts to "subclass" Error by running
`MyError.prototype = new Error();`, then the internal v8::Message object
that's produced and handed off to `window.onerror` handlers is poorly
stringified as "[object Object]".
This patch adjusts the stringification process for these objects to
include not only native Error objects, but also objects that have Error
in their prototype chain, and haven't overwritten Error.toString with
some custom variant.

I found this working on
...
https://codereview.chromium.org/19541010/
The main problem is that if you called Object.getNotifier(obj) on an object, %SetObserved(object) would never get called on it, and thus it would be unobservable (new test added for this).
Additionally, Runtime::SetObserved was asserting obj->IsJSObject() which would fail if called on a proxy.
It just happens that our existing test always called getNotifier() before Object.observe on proxies, and thus we never previously attempted to transition the map of a proxy.
Both issues are now fixed and properly tested.

Extract hardcoded error strings into a single place and replace them with enum.
...
I'd like to propagate bailout reason to cpu profiler.
So I need to save it into heap object SharedFunctionInfo.
But:
1) all bailout reason strings spread across all the sources.
2) they are native strings and if I convert them into String then I may have a performance issue.
3) one byte is enough for 184 bailout reasons. Otherwise we need 8 bytes for the pointer.
Also I think it would be nice to have error strings collected in one place.
In that case we will get additional benefits:
It allows us to keep this set of messages under control.
It gives us a chance to internationalize them.
It slightly reduces the binary footprint.
From the other hand the developers have to add new strings into that enum.

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.

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.

Fix HType handling for HConstant with external references.

constructor.
This patch adds an optional type parameter to the HValue,

This patch also removes the implicit recursion on phi operands,
using a loop and a worklist instead, to avoid potential stack

Simplify sampling rate calculation
...
Sampling rate is now calculated as total number of samples divided by profiling time in ms. Before the patch the sampling rate was updated once per 100ms which doesn't have any obvious advantage over the simpler method.
Also we are going to get rid of the profile node self and total time calculation in the v8 CPU profiler and only expose profiling start/end time for CpuProfile and number of ticks on each ProfileNode and let clients do all the math should they need it.

Fix for V8 issue 2795: Check fails with deopt for mjsunit/array-store-and-grow
...
(https://code.google.com/p/v8/issues/detail?id=2795 )
The reason is when allocating and building arrays in hydrogen we need to ensure
we do any int32-to-smi conversions BEFORE the allocation. These conversions can
at least theoretically deoptimize. If this happens before all the fields of the
newly allocated object are filled in, we will have a corrupted heap.
