e8320f4f78 Function::GetScriptOrigin should supply sourceURL when script name is not available. 
GetScriptOrigin is used for DevTools instrumentation.

If inspected call-site is inside "eval" then returned script name is "undefined". To fix this problem we can use the "nameOrSourceURL" method of script-wrapper.

This is a re-upload of https://codereview.appspot.com/6811090/ for the purpose of landing.

36d128d7b8 Reshuffle an if() condition to not depend on an uninitialized value. 
Node::class_id_ contains garbage for newly allocated (FREE) nodes. This patch
changes the code to first test the node state_, then (for non-FREE nodes),
class_id_, and not the other way around.

This does not affect the branch taken (i.e. the current code is correct),
but makes Valgrind and MSan happy.

c203f05474 Delivery logic for Object.observe 
This CL has two parts: the first is the logic itself, whereby each observer callback is assigned
a "priority" number the first time it's passed as an observer to Object.observe(), and that
priority is used to determine the order of delivery.

The second part invokes the above logic as part of the API, when the JS stack winds down to
zero.

Added several tests via the API, as the delivery logic isn't testable from a JS test
(it runs after such a test would exit).

bd4e114b8e Add code again to allow reclaiming old unexecuted functions. 
When code objects in the heap for FUNCTIONs and OPTIMIZED_FUNCTIONs are marked by the GC, their prologue is patched with a call to a stub that removes the patch. This allows the collector to quickly identify code objects that haven't been executed since the last full collection (they are the ones that sill contain the patch). The functionality is currently disabled, but can be activated by specifying the "--age-code".

This fixes a corner case when the instance prototype of a function is

the intial map to be unrelated for functions with the same shared info
and hence the shared construct stub is no longer generic enough to work

e405ff84b4 ES6: Adding support for size to Set and Map 
Section 15.14.5.10 and 15.16.5.7 in the October 26, 2012 ES6 draft,
http://wiki.ecmascript.org/doku.php?id=harmony:specification_drafts

This adds a getter for "size" to Set.prototype and Map.prototype which reflects
the number of elements in the Set and Map respectively.

c54fc70f13 Store Object.observe state per-isolate rather than per-context 
This requires adding a new JSObject to the strong root list and populating it from
object-observe.js. The main other change is that we now directly use ObjectHashTable
from JS rather than using WeakMap, since using the latter would end up leaking whichever
Context initialized that observation state.

Added a test via the API showing that different contexts all end up working on the same state.

b80cbd7922 Object.observe: generate change records for named properties. 
In more detail:
- Set observation bit for observed objects (and make NormalizedMapCache respect it).
- Mutation of observed objects is always delegated from ICs to runtime.
- Introduce JS runtime function for notifying generated changes.
- Invoke this function in the appropriate places (including some local refactoring).
- Inclusion of oldValue field is not yet implemented, nor element properties.

Also, shortened flag to --harmony-observation.

deprecated utility functions.

Previously Crankshaft emitted a generic load for these, now we emit a load of a
named field, guarded by a proto chain check.

LCheckPrototypeMaps now returns the holder, which is for free, because it
already had to check its map as the last step, anyway. This is in sync with what
StubCompiler::CheckPrototype does.

60267da6d9 MIPS: Cleanup handling of shifts: SHR can deoptimize only when its a shift by 0, all other shift never deoptimize. 
Port r12373 (9fdde2ad)

Original commit message:
Fix DoDeferredNumberTagU to keep the value in xmm1 instead of xmm0 on x64.

xmm0 is not saved across runtime call on x64 because MacroAssembler::EnterExitFrameEpilogue preserves only allocatable XMM registers unlike on ia32 where it preserves all registers.

Cleanup handling of shifts: SHR can deoptimize only when its a shift by 0, all other shift never deoptimize.

Fix type inference for i-to-t change instruction. On X64 this ensures that write-barrier is generated correctly.

ebb44f0d30 Expose gc(true) to JavaScript, which triggers a scavenger GC. 
With the --expose_gc option, gc() is exposed to JavaScript. Currently gc() triggers a full GC.

To enable JavaScript to test the behavior of a scavenger GC, this patch exposes gc(true). If the first argument is true, gc(...) triggers a scavenger GC. Otherwise, gc(...) triggers a full GC.

BUG=
Test=Manually confirmed that gc() and gc(false) trigger a full GC and that gc(true) triggers a scavenger GC.

37759f4d64 Implement committed physical memory stats for Linux. 
The patch introduces CommittedPhysicalMemory function to
the Heap class that reports committed *physical* memory acquired
for the heap from the OS.
It is important because some OSes may defer actual committment on e.g.
first access to the region.
So reporting just plain committed size led to various weird artifacts
like showing V8 allocated memory higher than the whole process
private size.

d247c5e6c7 Change constant pool marker to be the unconditional, permanently undefined instruction. 
The previously-used instruction isn't guaranteed to always be undefined,
and the encoding used was conditional (failing the condition on an
undefined instruction is itself undefined and not guaranteed to
fault!). I would have like to use a more clever encoding (see bug 2963),
but we need the extra bits to encode the size of the constant pool.

43e248d2e5 Use movw/movt instead of constant pool on ARMv7. 
Some ARM architectures load 32-bit immediate constants more efficiently using movw/movt pairs rather than constant pool loads. This patch allows the assembler to generate one or the other load form at runtime depending on what is faster.

9dc2c5b83d Add an API for enumerating persistent handles 
This API lets the embedder enumerate handles that have class ids. WebKit will
use this feature during garbage collection to compute object groups for DOM
nodes. Previously, we kept a list of DOM nodes on the WebKit side, but that
list is redundant with the global handles list in V8.
