Use ScopedArenaAllocator in BCE, DCE, LSE, ...

... ReferenceTypePropagation and GraphChecker.

Define and use a new allocation kind for LoadStoreAnalysis.

Memory needed to compile the two most expensive methods for
aosp_angler-userdebug boot image:
  BatteryStats.dumpCheckinLocked() : 19.7MiB -> 19.6MiB (-79KiB)
  BatteryStats.dumpLocked(): 39.4MiB -> 39.3MiB (-120KiB)

Test: m test-art-host-gtest
Test: testrunner.py --host --optimizing
