This harness function is not necessary in the majority of cases in which
it is used. Remove its usage to simplify tests and decrease the amount
of domain-specific knowledge necessary to contribute to the test suite.

Persist the harness function itself for use by future tests for ES2015
modules (such a helper is necessary for tests that are interpreted as
module code).

This commit normalizes the test case format used across test262. It applies the following transformations:

* Convert to YAML for frontmatter
* Remove of trailing whitespace
* Replace /r/n with /n except in chapters 6 and 7.
* Copyright header always uses // comments
* new includes attribute replaces $INCLUDE
* No implicit assumptions about test environment other than $ERROR. Everything else appears in the include array. This includes "runTestCase" which is now included in a substantial number of tests.

All Microsoft-contributed *.js and *.py sources now have Ecma's copyright header.

77 new (mostly) strict mode tests plus the removal of one invalid test case.

Sputnik and IE Test Center tests now live side-by-side in ch* directories under test/suite.

source starting NOW, to test/suite.
