We were hitting a compiler DCHECK that a class would never require to

was not trying to resolve a type, but instead relied on the verifier
for pre-populating the dex cache. However, the verifier doesn't
necessarily run in JIT mode.

This fixes a race between inlining in the Optimizing
backend and dex-to-dex quickening where the Optimizing can
read the non-quickened opcode and then the quickened field

Even if we such tearing of the dex instruction does not
happen, the possible reordering of dex-to-dex and Optimizing
compilation makes the final oat file non-deterministic.

Put boot class loader classes and strings in dex cache of app images.
The reason for b/
28295348 was that an ArtMethod of the boot image was
in the app image dex cache, but the declaring class of that
boot image method was not.
Since objects of boot images don't need fixups, the comparisons for
FixupStrings and FixupResolvedTypes was always false for them.

Fix profile saver initial wait
Was using TimedWait for the initial wait, but this can return
early if the process receives any interrupt (due to futex). The
solution is to use a wait loop. If the wait returned early, not
enough classes were including in the profile. This negatively
affected application launch times in some scenarios.
Sample wait times before the change:
Waited 2.002s

The PreSetup pass for opening an oatfile with dlopen parses all
shared objects and tries to retrieve the corresponding mem map
(so as to have a fake MemMap to reserve the space for any scanning
operations and so on). Optimistically optimize this pass by counting
the number of shared objects before the dlopen, and skipping as
many afterwards.

Adjust ProfileSaver strategy
Change to a notification based strategy (instead of polling):
- the JIT notifies the ProfileSaver everytime it attempts a compilation
or generate (in a task) a ProfileInfo object for the method
- once a certain number of hot methods notification are received,
ProfileSaver wakes up the thread to do the analysis
- a wake up does not equal to I/O since the during processing we might
realized that's actually not enough new data.
- ProfileSaver throtles the request and ensures it doesn't do the
processing more often than kMinSavePeriodNs.
The new strategy avoids waking the thread unnecessary during extended
idle periods when we don't JIT.
