dcfc514c38 Improve yield support and restrict usage of strict
- Partially reverting 91cdb93e57 and eaf3911c31 and reimplement
- Add generators support for objects and classes
- Only classes can have static methods so restrict use of it

Special thanks to @rvanvelzen and @kzc for reviewing this patch and
providing constructive feedback over and over again.

27eedbc302 Never produce -0 when evaluating expressions (like -"")
Fix for #1085. The major case was already there, but more expressions can result in -0.

8571a08a93 Do not attempt evaluating class expressions
Broadly the same as function expressions - these actually are statements but
we're limited by the inheritance tree.

634f231b78 First class block scope
- Make let, const, and class symbols be declared in a block scope.
- Piggy back on existing catch symbol implementation to get block-aware mangling working
- Make sure unused block-scoped declarations can be dropped
- Don't eliminate a block if it has a block-scoped declaration
- Remove silly empty anonymous blocks left over from drop_unused
- AST_Toplevel now gets to call drop_unused too, since block-scoped variables aren't global!
- Don't consider block declarations global
