ART: Release inputs in Long.reverse intrinsic in x86
In the worst case we are using two temps each for input and output.
Then we do not have a temp left over for the swap operations. The
input is dead, however, after the first swap. So try to release it
(a no-op if it isn't actually a temp).

ART: Compacting ROS/DlMalloc spaces with semispace copy GC
Current semispace copy GC is mainly associated with bump pointer
spaces. Though it squeezes fragmentation most aggressively, an extra
copy is required to re-establish the data in the ROS/DlMalloc space to allow
CMS GCs to happen afterwards. As semispace copy GC is still stop-the-world,
this not only introduces unnecessary overheads but also longer response time.
Response time indicates the time duration between the start of transition
request and the start of transition animation, which may impact the user
experience.
Using semispace copy GC to compact the data in a ROS space to another ROS(or
DlMalloc space to another DlMalloc) space solves this problem. Although it
squeezes less fragmentation, CMS GCs can run immediately after the compaction.
We apply this algorithm in two cases:
1) Right before throwing an OOM if -XX:EnableHSpaceCompactForOOM is passed in
as true.
2) When app is switched to background if the -XX:BackgroundGC option has value
HSpaceCompact.
For case 1), OOMs are significantly delayed in the harmony GC stress test,
with compaction ratio up to 0.87. For case 2), compaction ratio around 0.5 is
observed in both built-in SMS and browser. Similar results have been obtained
on other apps as well.

String.IndexOf method handles negative start index value in incorrect way
The standard implementation of String.IndexOf converts the negative value of
the start index to 0 and searching will start from the beginning of the string.
But current implementation may start searching from the incorrect memory
offset, that can lead to sigsegv or return incorrect result.
This patch adds the handler for cases when fromIndex is negative.

Avoid verifier crash for quickened invoke on null.
When verifying an invoke-virtual-quick on a "null" instance, we can't infer the
class of the method being invoked. This CL handles this case and avoid a crash
due to a failed check in RegType::GetClass.
Also revert changes made to test 082-inline-execute since it succeeds with this
CL now.

Fix test failure in SMART mode.
Update test 082-inline-execute to avoid a verifier issue with quickening.
An invoke-virtual is quickened into an invoke-virtual-quick. However it is
made on a "null" instance. During verification, we can't infer the method
being invoked from the vtable index since we have no access to the class. This
leads to fail on a check and abort.
