38f2d25a84 Ensure that interruptor callback registered through API is called outside of ExecutionAccess lock. 
Such a coarse locking can cause a dead-lock when another thread is attempting to clear an interrupt while we are waiting in the interrupt callback.

Add test that verifies this API invariant.

35b8b0b27a 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().

ecadc63b60 Partial revert of "Next bunch of fixes for check elimination". 
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.

fe243379f8 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.
 - CPUFeature enum values no longer map to CPUID bit fields.

11b8551f60 Parser / PreParser: Simplify error message arguments. 
In some places, we pretended that there can be multiple arguments, though in
practice there was only one. In other places (most importantly, PreParser), we
only handled one argument. (This means that we were not able to produce a
multi-argument error inside a lazy function anyway.)

This CL makes it clear that there is ever only one argument.

d51e48dced MIPS: Fix FlooringDivByPowerOf2I. 
Port r21313 (3b4cb0b)

Original commit message:
Fix for divisor=1, found during code inspection. We can't hit this bug, due to
HDiv::Canonicalize() discarding the operation, but it might avoid a future bug
hunt. Patch also includes a small tidying of the ARM64 code.

c0ec7f20c8 Mark slow mozilla test. 
This test is the remaining low hanging fruit in quick check and blocks the runner for 5 extra seconds.
