MIPS: Avoid flushing the icache unnecessarily when updating target addresses in code.
Port r21380 (ef20a0a)
Original commit message:
This CL updates RelocInfo update operations and set_target_address_at to enable

Code::CopyFrom and Code::Relocate are modified to avoid individual icache
flushes since the whole code area will be flushed after the reloc info is
updated.
These changes reduce a regression when enabling the OOL constant pool on Arm,

ES6 Map/Set iterators/forEach improvements
This changes how Map/Set interacts with its iterators. When the
underlying table is rehashed or cleared, we create a new table (like
before) but we add a reference from the old table to the new table. We
also add an array describing how to transition the iterator from the
old table to the new table.
When Next is called on the iterator it checks if there is a newer table
that it should transition to. If there is, it updates the index based
on the previously recorded changes and finally changes itself to point
at the new table.
With these changes Map/Set no longer keeps the iterators alive. Also,
as before, the iterators keep the underlying table(s) alive but not the
actual Map/Set.

Move microtask queueing logic from JavaScript to C++
This avoids the appearence of a leak due to storing a JSObject
as the microtask_state in the strong root list, and allows callers
to call Isolate::RunMicrotasks() without having any v8::Context
available (as at least Blink has interest in doing).
The queue is now a strong root, represented as a FixedArray of JSFunctions
(or empty_fixed_array, if it's empty); it doubles in size when it needs to grow.
The number of elements in the queue is stored in Isolate::pending_microtask_count().

Decouple CpuFeatures from serializer state.
Traditionally, we cross compile a snapshot iff the serializer is enabled.
This will change in the future.
Changes:
- CpuFeatures probing is done once per process, depending on whether we
cross compile.
- CpuFeatures are consolidated into the platform-independent assembler.h
as much as possible.
- FLAG_enable_<feature> will only be checked at probing time (already the
case for ARM).
- The serializer state is cached by the MacroAssembler.
- PlatformFeatureScope is no longer necessary.

Introduce a dynamic process pool for the local test driver
The new process pool allows adding jobs after testing has been started. It will also allow to restructure building the job queue (in a follow up CL), so that testing can start instantly while the queue is being built.
Also attempts to clean up the keyboard-interrupt logic. Idea: Only catch keyboard interrupt once per process at the outermost level. Use proper "finally" clauses to clean up everywhere where a keyboard interrupt might occur. Never turn named exceptions into none-exceptions using anonymous "raise".

Remove a race between sweepers and the free space skipping code (while iterating new space pointers).
There has been a race between a sweeper setting the next pointer on
free list node and the main thread skipping free space during update of
new space pointers in the heap.
This change removes the free space skipping code.
