Allow unlabelled function declarations outside of top level also in strict mode, and treat them as in non-strict mode (i.e., hoist). Previously they were rejected with SyntaxError in strict mode. The lenient behavior is better because it accepts more real world code. Ideally function declarations in strict mode would have block visibility, but that's not yet implementable.

Accept unlabelled function statements outside of top level for strict functions (using hoist semantics), previously they were rejected with a SyntaxError. This improves compatibility with some real world code.
