Use ScopedArenaAllocator for code generation.
Reuse the memory previously allocated on the ArenaStack by
optimization passes.
This CL handles only the architecture-independent codegen
and slow paths, architecture-dependent codegen allocations
shall be moved to the ScopedArenaAllocator in a follow-up.
Memory needed to compile the two most expensive methods for
aosp_angler-userdebug boot image:
BatteryStats.dumpCheckinLocked() : 19.6MiB -> 18.5MiB (-1189KiB)
BatteryStats.dumpLocked(): 39.3MiB -> 37.0MiB (-2379KiB)
Also move definitions of functions that use bit_vector-inl.h
from bit_vector.h also to bit_vector-inl.h .
Test: m test-art-host-gtest

ART: Add arena tracking mode
Add an arena tracking mode to get better insight into allocation
behavior. In this mode, the default size of arenas is very small
so that arena use for multiple places is limited. At the same time,
do not release arenas back into their pool and instead free them.
Tracking in this context is wrt/ tools that analyze calls to
allocation routines, e.g., massif and heaptrack. The goal of this CL
is to enable more precise tracking with such tools. The smaller
minimal arena sizes and deallocation instead of reuse will lead
to actual malloc calls instead of bump-pointer behavior, exposing
ArenaAllocator-based allocation to such tools.
To limit the build-time impact of switching tracking, add an -inl
file for the arena allocator that defines the controlling flag and
the default arena size.

ART: Fix ArenaStack::AllocWithMemoryTool().
MEMORY_TOOL_MAKE_NOACCESS() takes the size of the address
range as the second argument, not the end the range.

ART: Fix arena allocation for valgrind.
Move the zero-initialization check after marking the newly
allocated chunk as defined and check only the allocated
space without the red zone. Also mark unallocated space as
inaccessible instead of just undefined.

ART: Mark deallocated arena memory as inaccessible.
Mark arena and scoped arena memory freed by allocator
adapters as inaccessible. This can help catch accesses to
old storage of a container, for example the old data of an
ArenaVector<> that's been resized.
Together with debug-mode enforcement of destruction of all
scoped arena containers, this provides strong verification
of their memory usage. However, this does not apply to the
normal (non-scoped) arena memory held by arena containers
as they are typically not destroyed if they are themselves
located in the arena. ArenaBitVector memory, whether in
normal or scoped arena, isn't marked either.

Generalize Valgrind annotations in ART to support ASan.
Also add redzones around non-fixed mem_map(s).
Also extend -Wframe-larger-than limit to enable arm64 ASan build.

Move arenas into runtime
Moved arena pool into the runtime.
Motivation:
Allow GC to use arena allocators, recycle arena pool for linear alloc.
