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().

This reverts the part of r21154 that introduced the CHECK()s to verify
state of objects with stable maps during code generation. The CHECK()s
seem to trigger a non-critical hidden bug in the map stability
mechanism. We will re-add these CHECK()s once the bug is found and
fixed.

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.
 - CPUFeature enum values no longer map to CPUID bit fields.

CPUFeatures::Probe has been modified such that it can be called only once, but
the cctests make two calls in native builds: once in VM init, and once in each
test setup. This patch removes the call in the test setup.

Use the same keyboard interrupt logic as run-tests.
Close the perf database explicitly after one run, as it has two runs on the same architecture. Currently the first run closes on garbage collection, which might corrupt the second run.
