And perform in-place fixup of references and pointers. This
dirties all the boot image memory loaded by zygote, so there
shall be no "shared clean" boot image pages anymore, these
shall change to "shared dirty". However, as we're using a
profile-based boot image, these pages are presumably used
often enough and unlikely to be paged out anyway.
The in-place fixup takes around 60-120ms when starting the
zygote on aosp_taimen-userdebug. However, an experiment with
MAP_POPULATE pushes the raw fixup down to around 12-15ms.
If we used compressed images, this would be the actual time
for fixup as the data would be already present in memory.
If we keep using uncompressed images, we shall need to tune
the loading with MAP_POPULATE or MADV_WILLNEED.
The -Xrelocate/-Xno-relocate option is re-interpreted from
"use patchoat if needed" to "relocate the boot image in
memory if possible". We do not allow relocation for the AOT
compilation to speed up dex2oat execution and help producing
deterministic output.
The patchoat tool shall be removed in a follow-up CL.

Allow taking verification state from the oat file durin compilation
if the class is a dependency (thus not being compiled itself). This
is necessary in case the dependency itself has been quickened and
stripped, as quickened bytecodes are not supported during compile-
time verification.
Expose this through the CompilerCallbacks.

In preparation for extending the type check bit string from
24 to 28 bits, rewrite ClassStatus to fit into 4 bits. Also
perform a proper cleanup of the ClassStatus, i.e. change it
to an enum class, remove the "Status" word from enumerator
names, replace "Max" with "Last" in line with other
enumerations and remove aliases from mirror::Class.

By doing class unloading after each dex file compilation, we are loosing
away verification done on classpath classes.
This change introduces a new table for keeping around class status of
classpath classes.
Multidex quickening compilation improved by ~5% by not re-verifying classpath
classes.

Support class unloading for the quicken compilation filter. This will
be enabled in a follow up CL.
Added a test that compares with and without unloading. The way that
it tests this is by adding an output app image. Having an app image
disables the unloading. This test also covers that app images don't
change the odex (currently).
Added a test for the assumed verified logic.

MethodVerifier tests whether a DEX method is valid w.r.t. the classes
in class path. Since the APK does not change across OTA updates, it
is not necessary to analyze the bytecode again with MethodVerifier,
as long as its dependencies on the class path (which may have changed)
are satisfied.
This patch introduces VerifierDeps, a class path dependency collector,
and adds hooks into MethodVerifier where classes/methods/fields are
resolved and where assignability of types is tested.

Change the return type of MethodVerified to void. It was never
used anyways.
Remove the callbacks calls from the core of the verifier (Verify()).
Instead, make the convenience functions do the work, and add a
parameter to supply the callback so that the verifier becomes
independent of the Runtime-stored one.
Fix up calls that now need to provide a callback, but leave places
that only run the verifier to get metadata (e.g., register type data,
lock state) without callback. This avoids callback calls when in JIT
mode.

Use an actual PathClassLoader when compiling apps, instead of a
side structure and cutout.
This CL sets up a minimal object 'cluster' that recreates the Java
side of a regular ClassLoader such that the Class-Linker will
recognize it and use the internal native fast-path.
This CL removes the now unnecessary compile-time-classpath and
replaces it with a single 'compiling-the-boot-image' flag in the
compiler callbacks.
Note: This functionality is *only* intended for the compiler, as
the objects have not been completely initialized.

Add a pair of runtime flags -Xrelocate and -Xnorelocate that can force
the runtime to require that all files that are run are relocated, to
prevent attacks based on the known art base address.
Add support for running patchoat on oat files compiled without an image.
Change run-test to have new --prebuild and --relocate flags.

Fix clang build errors aswell as restructure locking/mutex code for correct
thread safety analysis support.
Reorder make dependencies so that host builds build first as they should
provide better compilation errors than target.
Remove host's use of -fno-omit-frame-pointer as it has no value with correct
use of CFI, which we should have.

We want to detect small methods for inlining at the end of
the method verification. Instead of adding more compiler
code to the runtime, we create a callback from the runtime
into the compiler, so that we can keep the code there.
Additionally, we move the compiler-related code that was
already in the method verifier to the compiler since it
doesn't really belong to the runtime in the first place.
