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
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.

adamk@chromium.org [Tue, 20 May 2014 14:22:05 +0000 (14:22 +0000)]
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.
