The Dex builder can now generate calls to methods (although not in all forms
yet). To help do this, we add a new virtual Instruction and Value class. This is
needed to generate code with values that are not known until the entire method
has been generated. In particular, we can now refer to function parameters.
The test method now accepts a String and returns the the length of the string.

This is planned to ship on device, so by convention the view_compiler should not
be in a tools directory.
Change-Id: I0eb03812d77ec38edc3908725acb40bacb345ecd
This change begins work on DexBuilder, which will allow us to generate DEX files
directly from layouts. This version is rather limited, but we will expand its
functionality in future CLs. The DexBuilder in this CL can create a DEX file
from scratch, define classes, and define methods on those classes. Within
methods, it supports extremely simple instructions, such as storing a small
constant in a register and returning a value from a register. Additionally,
there are tests to make sure that at least at a structural level, the generated
DEX files are valid.
DexBuilder and its associated builder classes use functionality from
libartdexfile and the Dex Slicer tool to support the actual encoding of DEX
files.
Test: atest, also manually tested by loaded a generated DEX file in an Android
app and verifying its behavior.

Also add support for temporarily disabling selinux
while running the iorap binder integration tests.
Test: atest --test-mapping frameworks/base/startop/iorap

Connects to the binder 'iorapd' service as a client
and tests round-trip callback functionality.
Also adds mockito-inline to the test build, allowing us to mock
any class/methods, even if it's static or final.
Note: selinux is currently not supported, need to use
$> adb shell setenforce 0
Prior to running any tests relying on binder connectivity.

This is an initial step towards a tool for pre-compiling layout XML files. It
accepts an XML file and produces a Java language class called CompiledView with
a static method, inflate. Calling CompiledView.inflate should then return a view
object that is equivalent to calling LayoutInflater.inflate on the same
resource.
There are still several important limitations, but this works well enough to do
some experimentation. The limitations include:
* Currently only one layout can be compiled at a time.
* `merge` and `include` nodes are not supported.
* View compilation is a manual process that requires code changes in the
application.
* The tests in this CL do not yet exercise any interesting behavior.

Fix remote_pkill function to work on multiple pids,
this was breaking chrome (which has 3 pids).
Fix activity inference to the "$pkg/$activity"
pattern where previously it could accidentally parse
the wrong token.
Fix app launching to handle activities with '$' in
the name which adb shell treated as a variable.

Adds a new script which is used by app_startup_runner.py and
run_app_with_prefetch in order to force the compilation filter.
Example:
$> ./query_compiler_filter.py --package com.google.android.calculator
speed-profile unknown arm64
(For example compiling to speed is extremely slow, compiling to
speed-profile is just marginally slow.)
Matching the compiler filter with what we actually need to measure is
extremely important as the performance will vary greatly.
Change-Id: I78ae76504208a672a7d17bab5001d11ab796d9d4
Example: ./force_compiler_filter --package com.google.android.apps.maps --compiler-filter speed-profile
Run the app just slightly enough to fully start up, then force it to
dump the profile and recompile the application with dex2oat under the
speed-profile filter.
(Also supports any other compilation filter such as quicken, speed,
etc).
Subsequently, this command can be used to manually validate that the
compiler filter was indeed changed:
$ adb shell dumpsys package com.google.android.apps.maps | grep -A10 "Dexopt state"
Dexopt state:
[com.google.android.apps.maps]
path: /data/app/com.google.android.apps.maps-D7s8PLidqqEq7Jc7UH_a5A==/base.apk
arm64: [status=speed-profile] [reason=unknown]
Test: Manual (see above)
