Annex b skip fib (#704)

Browse Source 
* Re-generate tests

The test generation tool has been modified in the time since these tests
were first generated and committed to the project. Re-generate the tests
using the latest version of the tool.

* Add test cases for Annex B hoisting disqualifiers

The "variable-like" function hoisting semantics defined in Annex B
extension B.3.3 is only applied if "[...] replacing the
FunctionDeclaration f with a VariableStatement that has F as a
BindingIdentifier would not produce any Early Errors [...]". Test262
previously included tests for this condition when the disqualifying
early error originated from the ScriptBody and FunctionBody productions.

Add test cases to assert the behavior when it is disqualified by all
other relevant early errors: Block statements, `for` statements,
`for-of` statements, `for-in` statements, and Switch statements.

* Generate tests

* fixup! Add test cases for Annex B hoisting disqualifiers

* fixup! Add test cases for Annex B hoisting disqualifiers

Correct test case "info" meta-data.

* fixup! Add test cases for Annex B hoisting disqualifiers

Improve test bodies

* fixup! Generate tests
