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.

Avoid flushing the icache unnecessarily when updating target addresses in code.

This CL updates RelocInfo update operations and set_target_address_at to enable
skipping of the icache flush if it going to be batched up later.
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,
since this change can cause MovT/MovW instructions for relocatable targets
if the constant pool is full.

Scores for Mandreel latency on a Nexus 5:
 - OOL CP disabled: 3533
 - OOL CP enabled, without this CL: 1825
 - OOL CP enabled, with change: 3015

Refactor transitioning stores.

There's actually no need to have the transition as part of the HStoreNamedField instruction. In fact, it is cleaner and faster to generate a separate HStoreNamedField for the transition map. This will also help to eliminate map stores with store elimination, as well as reduce register pressure for transitioning stores on ia32.

Get rid of HStoreNamedField::SkipWriteBarrier().

The write barrier elimination does the right thing now, so
we can get rid of this hack.

Parser: delay throwing errors.

This makes Parser a bit more independent of Isolate during the recursive descent
phase. That is necessary for making it possible to run Parser on a non-main
thread in the future.

Proof of concept CL for the the "Parser independent of Isolate" work is here:
