ART: Replace base/logging with android-base/logging
Replace wherever possible. ART's base/logging is now mainly VLOG
and initialization code that is unnecessary to pull in and makes
changes to verbose logging more painful than they have to be.

Use ScopedArenaAllocator for register allocation.
Memory needed to compile the two most expensive methods for
aosp_angler-userdebug boot image:
BatteryStats.dumpCheckinLocked() : 25.1MiB -> 21.1MiB
BatteryStats.dumpLocked(): 49.6MiB -> 42.0MiB
This is because all the memory previously used by Scheduler
is reused by the register allocator; the register allocator
has a higher peak usage of the ArenaStack.
And continue the "arena"->"allocator" renaming.

Do not refresh the Marking Register in CriticalNative methods.
CriticalNative methods shall not be suspended and hence do not
require MR to be refreshed in compiled JNI code.
This change is for ARM and ARM64 only.
Impact on Critical Native benchmarks times (median of 10 runs,
lower is better):
* angler-userdebug - ARMv7
** All cores
NativeDowncallStaticCritical -2.78%
NativeDowncallStaticCritical6 -1.79%
** Little cores only
NativeDowncallStaticCritical -1.66%
NativeDowncallStaticCritical6 -1.27%
** Big cores only
NativeDowncallStaticCritical -2.66%
NativeDowncallStaticCritical6 -1.70%
* angler-userdebug - ARMv8
** All cores
NativeDowncallStaticCritical -3.52%
NativeDowncallStaticCritical6 -1.79%
** Little cores only
NativeDowncallStaticCritical -1.63%
NativeDowncallStaticCritical6 -1.27%
** Big cores only
NativeDowncallStaticCritical -3.87%
NativeDowncallStaticCritical6 -1.75%

Instrument ARM64 generated code to check the Marking Register.
Generate run-time code in the Optimizing compiler checking that
the Marking Register's value matches `self.tls32_.is.gc_marking`
in debug mode (on target; and on host with JIT, or with AOT when
compiling the core image). If a check fails, abort.
Test: m test-art-target
Test: m test-art-target with tree built with ART_USE_READ_BARRIER=false
Test: ARM64 device boot test with libartd.

jni: Add read barrier fast path to jni compiler
Static method dispatch via JNI requires a read barrier
for the ArtMethod::GetDeclaringClass() load before adding it to the
JNI StackHandleScope.
We used to call ReadBarrierJni unconditionally but add a branch
to skip calling it if the GC is not currently in the marking phase.
Test: ART_USE_READ_BARRIER=true make test-art-host test-art-target

ART: Extract macro assembler
Extract macro assembler functionality used by the JNI compiler from
the assembler interface. Templatize the new interface so that
type safety ensures correct usage.
