collinsn@google.com 2ccac8093b Add language tests for Issue 18628.
As suggested by @karlklose in https://codereview.chromium.org/513563002/
comments.

Improve testing documentation.

- add a README
- add a description by example of selectors to the "./tools/test.py -h"
  output
- update/add source comments

I had a hard time figuring out how to add and run the tests, mostly
because I tried to call them "*_test_1.dart" and "*_test_2.dart", but
language test files must have names of the form "*_test.dart".  So, I
added a README summarizing and referencing the relevant docs.

Run Existing Tests
==================
See the output of
../tools/test.py --help
for how to run tests.
See also
https://code.google.com/p/dart/wiki/Building#Testing
for detailed examples.
Create New Tests
================
See comments above
factory StandardTestSuite.forDirectory
in
../tools/testing/dart/test_suite.dart
for the default test directory layout. By default test-file names must
end in "_test.dart", but some test suites, such as ./co19, subclass
StandardTestSuite and override this default.
See comments at the beginning of
../tools/testing/dart/multitest.dart
for how to create tests that pass by failing with a known error. For
example,
...
int x = "not an int"; /// 01: static type warning
...
as part of a test will only pass the "--compiler dartanalyzer" test if
the assignment generates a static type warning.
