Add tests that assert the management of the running execution context's
LexicalEnvironment and VariableEnvironment components, as created by the
following abstract operations:
- NewDeclarativeEnvironment
- NewObjectEnvironment
- NewFunctionEnvironment
Many tests require the use of non-strict direct eval, meaning they may
not be run in strict mode. This does not effect coverage because the
semantics in these cases are not observable from strict mode code.
Some situations require the creation of a binding, but this binding has
no relevance to the test itself. In these cases, use names consisting
solely of the underscore character (`_`).
Avoid the use of Block statements wherever possible, as these trigger
the creation of additional environments which may interfere with the
behavior under test.
Closes#572
Introduce tests for new semantics for ES2015 features such as
lexically-scoped bindings. Also add tests for semantics defined in prior
editions of the specification but not yet covered in this test suite.
Limit tests in `language/expressions/call/` and `built-ins/eval/` to
only assert details that are directly related to the invocation pattern.
Re-organize all other tests within the `language/eval-code/` directory,
further categorizing each as `direct` or `indirect` as appropriate.
Remove the extraneous "executable" flag from those files which carried
it.
ECMAScript 2015 introduced tail call optimization for function calls
occuring in a number of positions in the grammar. Assert expected
behavior by triggering a large (but configurable) number of recursive
function calls in these positions. Compliant runtimes will execute such
programs without error; non-compliant runtimes are expected to fail
these tests by throwing an error or crashing when system resources are
exhausted.

This change adds 'var' declarations for global variables to allow the tests to run in strict mode (see issue #35).
Extra care was taken to ensure the changes do not alter the test behavior, for example when implicit creation of global variables are part of the test.
Note: The change does not fix all strict mode errors due to missing 'var' declarations.
