Unittests may take compilation dependencies without committing them,
because no code object is ever created. This CL ensures that after each
unittest, all uncommitted dependencies are discarded. Without this,
the compilation dependencies leaks pointers to already freed C++ objects
between test-cases, which are then accessed after free if a unittest
invalidates the corresponding compilation dependency.

Currently we perform the full iteration protocol even when we don't need
to. When IterableToListCanBeElided is true, we still need to create a
copy of the array (from a spec correctness point of view, in case there
are user-JS side-effects that would modify the original).

This CL copies the array directly, skipping the iteration protocol.
This recovers the JSTests/TypedArrays/ConstructArrayLike benchmark
almost completely.

Migrate the Object.getOwnPropertyNames to the CodeStubAssembler and use the enum cache backing store when
1) the enum cache is avaible
2) the {object} has no elements
3) all own properties are enumerable

This makes a speedup of 10x when using Object.getOwnPropertyNames with fast-path. It improves Speedometer2.0 Inferno case by ~9% on ATOM platform.

The method does not do much, and all callers actually overwrite or
delete the stack slot right after calling this method anyways, so there
is no need to make the slot a stack slot first.

As per https://github.com/whatwg/console/issues/27#issuecomment-289312546
and https://bugs.chromium.org/p/chromium/issues/detail?id=706804 we're
leaving the console timeline/timelineEnd methods out of the specification
and testing that implementations do not expose them (relevant WPTs at
https://github.com/web-platform-tests/wpt/blob/master/console/console-tests-historical.any.js).
Their implementations should be removed from Chrome, one of the last
implementers of these legacy methods. The same goes for markTimeline, as
it is deprecated in Chrome and not being included in the spec.

ArraySpliceTorque builtin triggers generation of MIPS specific
trampolines due to its large size, and this code is not PIC
and cannot be isolate independent.

This CL is a workaround that marks ArraySpliceTorque as
isolate dependent on MIPS64.

Before flipping the flag, some tests need to be adapted. This CL
