Zachary D. Rowitsch feadf268dc Add JavaScript for/while/do-while loops, ++/--, and compound assignment ...

Implement three loop types (for, while, do-while) with break/continue support,
increment/decrement operators (prefix/postfix), and compound assignment (+=, -=, *=).
Extract heavy execute_stmt match arms into #[inline(never)] helpers to prevent
debug-build stack overflow from enlarged stack frames.

Promotes 5 JS262 tests from known_fail to pass and adds 8 new conformance fixtures.
JS262 suite: 114 pass, 7 known_fail, 1 skip (122 total).
