New experimental GC stress mode
Tries to do a GC for every unique call stack (up to 16 frames).
The goal is to catch moving GC bugs and lock violations without being
rediculously slow. Some tests fail on 64 bits, 32 bit host doesn't
work. N5 is booting.
Added runtime -Xgc options: gcstress and nogcstress.

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.

Create OatFileAssistant class for assisting with oat files.
The oat file assistant is used for determining whether dex2oat or
patchoat is needed, for running dex2oat or patchoat as needed to make
an oat file up to date, and to load dex files associated with a given
dex location.
The introduction of the OatFileAssistant class is meant to clean up and
consolidate code related to the management of oat files that was
duplicated and spread across dalvik_system_DexFile.cc and
class_linker.cc.

ART: Fix "unused parameters"
GCC 4.8 decides that parameters for functions implemented with
"= default" are unused. This currently only impacts x86, but remove
the parameter names anyways.

Add JIT
Currently disabled by default unless -Xjit is passed in.
The proposed JIT is a method JIT which works by utilizing interpreter
instrumentation to request compilation of hot methods async during
runtime.
JIT options:
-Xjit / -Xnojit
-Xjitcodecachesize:N
-Xjitthreshold:integervalue
The JIT has a shared copy of a compiler driver which is accessed
by worker threads to compile individual methods.
Added JIT code cache and data cache, currently sized at 2 MB
capacity by default. Most apps will only fill a small fraction of
this cache however.
Added support to the compiler for compiling interpreter quickened
byte codes.
Added test target ART_TEST_JIT=TRUE and --jit for run-test.
TODO:
Clean up code cache.
Delete compiled methods after they are added to code cache.
Add more optimizations related to runtime checks e.g. direct pointers
for invokes.
Add method recompilation.
Move instrumentation to DexFile to improve performance and reduce
memory usage.

Passes JDWP options to debugger on runtime init so we no longer need
to keep them on the heap.
Updates ParseJdwpOption to return Result for consistency.

Read JDWP options from runtime
Allocates JDWP::JdwpOptions on the heap and copies parsed options to
avoid the need to include jdwp/jdwp.h into runtime.h file.
Also does some minor cleanup and removes the old JDWP options parsing
code that became dead code after we move it to the new command-line
parser.

art: Refactor RuntimeOptions/ParsedOptions
Refactor the RuntimeOptions to be a
type-safe map (VariantMap, see runtime_options.h) and the ParsedOptions
to delegate the parsing to CmdlineParser (see cmdline/cmdline_parser.h).
This is the start of a command line parsing refactor, and may include
more in the future (dex2oat, patchoat, etc).
For more details of the command line parsing generator usage see cmdline/README.md
