MIPS: Turn off allocation site info for crankshafted array constructor calls.
...
Port r14934 (dbddd7e)
Original commit message:
Once we crankshaft a method, we should turn off allocation site info for
constructed arrays. Additionally, the semantics for doing this were
awkward because the constructed array code stubs get an
AllocationSiteMode as a minor key, but it's used as a permission to
determine the final mode locally based on ElementsKind. I refactored
this to a simpler boolean for override or local control.

CPU profiler should support names of accessors set via v8::Object::SetAccessor
...
This change fixes the case when the accessors are invoked from JSObject::{Get,Set}PropertyWithCallback.
It already works for inlined calls generated by StoreStubCompiler::CompileStoreCallback. The same still needs to be fixed for getter invocations generated by BaseLoadStubCompiler::CompileLoadCallback, corresponding case is commented out in the new test.
This is a slightly modified version of r14915 which was rolled back due to test timeout on Windows. Compared to r14915 the new tests use OS::TimeCurrentMillis instead of OS::Ticks as OS::Ticks has ms precision on Windows and trying to wait 10 ticks (us) will result in at least 1 ms pause.

Re-land: Implement ObservedArrayPop, ObservedArrayShift, ObservedArrayUnshift & ObservedArraySplice
...
Original issue: https://codereview.chromium.org/15331002/
Broke mozilla/js1_5/Array/regress-451483.js, which ends up attempting to call %IsObserved() on a non-object.
IsObserved now checks for JSReceiver and returns false rather than crashing.

[
CL breaks mips, since the deoptimizer in Deoptimizer::DoTranslateCommand(...) does not convert smis passed to the stub via a0.
