Fix heap trimmer daemon sleeping.

Problem:
Heap trimmer daemon sleeping caused app launch occasionally to take a
while due stopping the heap trimming thread taking a long time.

The heap trimmer thread now never sleeps, we prevent issues caused
by frequent back and forth process state changes by only
transitioning to background if it has been kCollectorTransitionWait
time since the last transition to background. Similar logic for heap
trimming.

Quick compiler: Fix MIPS build

b/16484538

In debug builds, the Quick compiler frequently runs a sanity checker
over the register pool.  Among other things, it attempts to verify
consistent representation of register pairs.  However, a register's
"wide" flag is meaningful only when the register pair is associated
with a Dalvik wide value (sreg != INVALID_SREG) rather than a temp
wide value.

The MIPS build was tripping over this bad assertion.  Fixed here.

Fix race condition in TransitionCollector.

There was a minor race condition that could happen if multiple
threads called TransitionCollector at the same time. Starting out
in CMS:

Thread 1: TransitionCollector(SS).
Thread 2: TransitionCollector(CMS) sees that it is already CMS so
has copying_transition == false. But then thread 2 changes to SS.
Thread 1 resumes but incorrectly doesn't check the
disable_moving_gc_count_ possibly resulting in errors if
disable_moving_gc_count_ != 0 due to JNI since we are going from
SS -> CMS and are goign to move objects.
