ART: Use ScopedArenaAllocator for pass-local data.
Passes using local ArenaAllocator were hiding their memory
usage from the allocation counting, making it difficult to
track down where memory was used. Using ScopedArenaAllocator
reveals the memory usage.
This changes the HGraph constructor which requires a lot of
changes in tests. Refactor these tests to limit the amount
of work needed the next time we change that constructor.
Test: m test-art-host-gtest
Test: testrunner.py --host
Test: Build with kArenaAllocatorCountAllocations = true.

Use mmapped boot image class table for PIC app HLoadClass.
Implement new HLoadClass load kind for boot image classes
referenced by PIC-compiled apps (i.e. prebuilts) that uses
PC-relative load from a boot image ClassTable mmapped into
the apps .bss. This reduces the size of the PIC prebuilts
that reference boot image classes compared to the kBssEntry
as we can completely avoid the slow path and stack map
unless we need to do the class initialization check.

Use mmapped boot image intern table for PIC app HLoadString.
Implement new HLoadString load kind for boot image strings
referenced by PIC-compiled apps (i.e. prebuilts) that uses
PC-relative load from a boot image InternTable mmapped into
the apps .bss. This reduces the size of the PIC prebuilts
that reference boot image strings compared to the kBssEntry
as we can completely avoid the slow path and stack map.
We separate the InternedStrings and ClassTable sections of
the boot image (.art) file from the rest, aligning the
start of the InternedStrings section to a page boundary.
This may actually increase the size of the boot image file
by a page but it also allows mprotecting() these tables as
read-only. The ClassTable section is included in
anticipation of a similar load kind for HLoadClass.
Prebuilt services.odex for aosp_angler-userdebug (arm64):
- before: 20862776
- after: 20308512 (-541KiB)
Note that 92KiB savings could have been achieved by simply
avoiding the read barrier, similar to the HLoadClass flag
IsInBootImage(). Such flag is now unnecessary.

MIPS32: Improve method invocation
Improvements include:
- CodeGeneratorMIPS::GenerateStaticOrDirectCall() supports:
- MethodLoadKind::kDirectAddressWithFixup (via literals)
- CodePtrLocation::kCallDirectWithFixup (via literals)
- MethodLoadKind::kDexCachePcRelative
- 32-bit literals to support the above (not ready for general-
purpose applications yet because RA is not saved in leaf
methods, but is clobbered on MIPS32R2 when simulating
PC-relative addressing (MIPS32R6 is OK because it has
PC-relative addressing with the lwpc instruction))
- shorter instruction sequences for recursive static/direct
calls
Tested:
- test-art-host-gtest
- test-art-target-gtest and test-art-target-run-test-optimizing on:
- MIPS32R2 QEMU
- CI20 board
- MIPS32R6 (2nd arch) QEMU
