Reason for revert:
Got one dev-channel with this. Should be enough.

This reverts commit 992751d0dc.
The final spec for Object.getPrototypeOf calls ToObject on the
parameter, which means that it should only throw for null and
undefined. For other non object values the prototype of the wrapper
should be used.
Difference from last time: Updated .status and will disable Blink
side tests as needed.

It triggers once per context that calls observe (or attempts to access

Original commit message:
This adds the basics necessary to support float32 operations in TurboFan.
The actual functionality required to detect safe float32 operations will
be added based on this later. Therefore this does not affect production
code except for some cleanup/refactoring.
In detail, this patchset contains the following features:
- Add support for float32 operations to arm, arm64, ia32 and x64
backends.
- Add float32 machine operators.
- Add support for float32 constants to simplified lowering.
- Handle float32 representation for phis in simplified lowering.
In addition, contains the following (related) cleanups:
- Fix/unify naming of backend instructions.
- Use AVX comparisons when available.
- Extend ArchOpcodeField to 9 bits (required for arm64).
- Refactor some code duplication in instruction selectors.

This ensures that all expressions that throw actually mark the current
environment as dead in the AstGraphBuilder. This prevents live ranges
from being unnecessarily increased by paths that don't fall-through.
Note that we can do that because Runtime::kThrowFoo never returns.

This changes the IrOpcode::kThrow operator to have kNoThrow property,
which sounds unintuitive, but holds for our graphs. The operators is
used to indicate exceptional control flow out of the function, but in
itself does not throw, the throwing is done by a runtime call.

Currently this only sets branch hints, so we get unlikely code "out of
the way", but in the long run the register allocator needs some love
to treat the unlikely code as, well, unlikely. :-)

The libdl library is already included on target builds of Android and needs
to be added to the build command line with a particular order to avoid
undefined references in other libraries. Fix this by only explicitly including
it in host builds and relying on the implicit inclusion on target builds.
Also remove the librt hack which is not longer necessary due to the AOSP build
bot having been removed.

Because simulators have a seperate JavaScript and C++ stack, and
because they try to avoid calling the runtime StackCheck function
on entry to every function, it can happen in recursive calls that
the C++ stack overflows while the JavaScript stack is okay. The
runtime StackCheck function would catch this, but as an optimization,
generated code only looks at the JavaScript stack pointer to
determine if it should make that runtime call.

The V8::IdleNotification will only return 'True' when the gc idle time handler
thinks there is no more GC which can be done. However, the gc idle task handler
can end up repeatedly making no progress (e.g., if it can't finalize a sweep)
which causes idle tasks to be repeatedly scheduled in Chrome which do nothing
but wake up Chrome. Fix this by returning Done if we can't make any progress
within an Idle Round.

We only report the usages when full parse is happening, i.e. only when the function that declares a legacy const is compiled. This is an approximation that is easy to implement, but still should reflect the real-world usage.
