Checker: Allow don't-care output on a line
This patch changes the behaviour of whitespace characters in CHECK
lines, allowing for additional content between verified parts of the
matched output line. Tests therefore won't need to explicitly match
attributes which are not tested.
The way attributes are printed ensures that the right part of the
line is matched against.
Example:
- output line: i32 Div [ i4 i8 ] ( loop_header:null )
- CHECK before: Div [ {{i\d+}} {{i\d+}} ] ( loop_header:null )
- CHECK now: Div ( loop_header:null )

ART: Run Checker with Python >2.6
Chromium buildbots don't have Python 3. This patch fixes the uses
of print() and ASCII vs. Unicode strings to make Checker compatible
with Python 2.6 and above.

ART: Logging levels for Checker
Small patch which enables Checker to print errors but not info
messages as opposed to the current all or nothing. This is useful for
running Checker with run-test.

ART: Fixed subsequent CHECK-NOTs Checker bug
Matching a group of CHECK-NOT lines caused Checker to crash due to
incorrectly overwriting the varState variable. The second use of the
variable was renamed and a regression test added.

ART: Improved fail reporting in Checker
Checker now keeps track of line numbers and prints more informative
log messages.

ART: New types of Checker assertions
Checker now supports positive out-of-order assertions (CHECK-DAG),
which are useful for matching dependency graphs, and negative
assertions (CHECK-NOT) to test element removal.
ConstantFolding tests are rewritten using -DAG checks and Inliner
tests are added.

ART: Added Checker, a pattern matching test engine
This patch adds a Python script which implements a domain-specific
mini-language similar to that of LLVM's FileCheck. It is primarily
intended for writing tests for the optimizing compiler but could be
configured for other use cases too. It is implemented from scratch in
order to avoid dependency on LLVM.
Checker tests are written in Java and dex2oat is invoked with a flag
which dumps the CFG before and after each pass of the optimizing
compiler. The output is then compared against assertions in the
test's comments parsed by Checker. See comments in tools/checker.py
for more details about the currently supported language features.
This initial CL implements only one type of assertion - whether the
output contains lines matching a desired pattern in the given order -
but supports both plain text and regex matching and allows for
equivalency testing by matching for the outcome of a previous match.
See the tests in compiler/optimizing/test/ConstantFolding.java for
examples.
