MIPS: Use Lsa/Dlsa when possible.
For MIPS32R6 replace instances of "sll/addu" to calculate the
address of an item in an array with "lsa". For other versions of
MIPS32 use the "sll/addu" sequence. Encapsulate this logic in an
assembler method to eliminate having a lot of statements like
"if (IsR6()) { ... } else { ... }" scattered throughout the code.
MIPS64 always supports R6. This means that all instances of
"dsll/daddu" used to calculate the address of an item in an array
can be replaced by "dlsa" so there is no need to encapsulate
conditional logic in a special method. The code can just emit
"dlsa" directly.
Test: mma -j2 ART_TEST_OPTIMIZING=true test-art-target-run-test
Tested on MIPS32, and MIPS64 QEMU.
Test: "make test-art-target-gtest32" on CI20 board.
Test: "cd art; test/testrunner/testrunner.py --target --optimizing --32"
on CI20 board.

MIPS32: Refactor implicit null checks in array/field get/set.
Rationale: on MIPS32 64-bit loads and stores may be performed
as pairs of 32-bit loads/stores. Implicit null checks must be
associated with the first 32-bit load/store in a pair and not
the last. This change ensures proper association of said checks
(a few were done after the last 32-bit load/store in a pair)
and lays ground for further improvements in array/field get/set.

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

ART: Clean up arm64 kNumberOfXRegisters usage.
Avoid undefined behavior for arm64 stemming from 1u << 32 in
loops with upper bound kNumberOfXRegisters.
Create iterators for enumerating bits in an integer either
from high to low or from low to high and use them for
<arch>Context::FillCalleeSaves() on all architectures.
Refactor runtime/utils.{h,cc} by moving all bit-fiddling
functions to runtime/base/bit_utils.{h,cc} (together with
the new bit iterators) and all time-related functions to
runtime/base/time_utils.{h,cc}. Improve test coverage and
fix some corner cases for the bit-fiddling functions.
Bug: 13925192

Implement CFI for JNI.
CFI is necessary for stack unwinding in gdb, lldb, and libunwind.

Add Handle/HandleScope and delete SirtRef.
Delete SirtRef and replaced it with Handle. Handles are value types
which wrap around StackReference*.
Renamed StackIndirectReferenceTable to HandleScope.
Added a scoped handle wrapper which wraps around an Object** and
restores it in its destructor.
Renamed Handle::get -> Get.

Allow mixing of thread offsets between 32 and 64bit architectures.

Doesn't implement 64bit thread offset support for the JNI compiler.

x86_64: JNI compiler
Passed all tests from jni_compiler_test and art/test on host with jni_copiler.
Incoming argument spill is enabled, entry_spills refactored. Now each entry spill
contains data type size (4 or 8) and offset which should be used for spill.
Assembler REX support implemented in opcodes used in JNI compiler.
Please note, JNI compiler is not enabled by default yet (see compiler_driver.cc:1875).

Object model changes to support 64bit.
Modify mirror objects so that references between them use an ObjectReference
value type rather than an Object* so that functionality to compress larger
references can be captured in the ObjectRefererence implementation.
ObjectReferences are 32bit and all other aspects of object layout remain as
they are currently.
Expand fields in objects holding pointers so they can hold 64bit pointers. Its
expected the size of these will come down by improving where we hold compiler
meta-data.
Stub out x86_64 architecture specific runtime implementation.
Modify OutputStream so that reads and writes are of unsigned quantities.
Make the use of portable or quick code more explicit.
Templatize AtomicInteger to support more than just int32_t as a type.
Add missing, and fix issues relating to, missing annotalysis information on the
mutator lock.
Refactor and share implementations for array copy between System and uses
elsewhere in the runtime.
Fix numerous 64bit build issues.

Entry point clean up.
Create set of entry points needed for image methods to avoid fix-up at load time:
- interpreter - bridge to interpreter, bridge to compiled code
- jni - dlsym lookup
- quick - resolution and bridge to interpreter
- portable - resolution and bridge to interpreter
Fix JNI work around to use JNI work around argument rewriting code that'd been
accidentally disabled.
Remove abstact method error stub, use interpreter bridge instead.
Consolidate trampoline (previously stub) generation in generic helper.
Simplify trampolines to jump directly into assembly code, keeps stack crawlable.
Dex: replace use of int with ThreadOffset for values that are thread offsets.
Tidy entry point routines between interpreter, jni, quick and portable.
