Refactor how embedded pointers are visited.

This refactoring (almost) gets rid of the requirement to get the target
object address for an object pointer embedded in code objects. This is
not possible on MIPS as pointers are encoded using two instructions. All
usages of RelocInfo::target_object_address() are (almost) obsoleted by
this change. The serializer still uses it, so MIPS will not yet work
with snapshots turned on.

Fix free list node ending up on evacuation candidate.

This is a temporary fix which avoids compaction when incremental marking
is restarted during an old-space-step. That could turn the page that
holds the chosen free list node into an evacuation candidate. It could
also cause several other inconsistencies if it happens during scavenge.

Refactor JSObject::SetFastElement.

This fixes a bug where the length of FAST_DOUBLE_ELEMENTS arrays was not
set correctly, and another bug where appending a double element to a
SMI_ONLY array would convert it to FAST_ELEMENTS instead of
FAST_DOUBLE_ELEMENTS.

Support for precise stepping in functions compiled before debugging was started (step 2)

This change will ensure that full code with debug break slots is compiled and activated for all functions which already have activation frames.

This additional handling is only for functions which have activations on the stack, and that activation is of the full code compiled without debug break slots. In that case the full code is recompiled with debug break slots. It is ensured that the full code is compiled generating the exact same instructions - except for the additional debug break slots - as before. The return address on the stack is then patched to continue execution in the new code.

Also fixed SortedListBSearch to actually use the passed comparision function.

Implement shrinking of paged spaces during sweeping.

For each paged space we release all but one of the unused pages after
marking (when we know the number of live bytes) but before actually
sweeping it. This is not yet done for lazy swept pages.

Don't need to protect pregenerated stubs from flushing from the
cache. They are in a different cache that is not flushed. Keep
the marking of pregenerated stubs for assertion purposes.

Small simplification of HChange instruction.

Use existing flag to mark HChange instructions that deoptimize on undefined.

Also there is no need to store the source representation explicitly.
