Use eq_ignore_ascii_case when parsing HTML tags. Different versions
of Flash may export HTML tags with different cases, so this will
work a little better; however, we'll need a true HTML parser to
handle this robustly (for opening and closing tags with different
cases, for example).
* Implement `add`, with tests.
* Implement `add_i`.
There's no test, because for whatever reason, I can't figure out how to emit this from Animate CC 2020.
* avm2: Implement `bitand` with tests.
* Implement `bitnot` with tests.
* Implement `bitor` with tests.
* avm2: Implement `bitxor`
* avm2: Implement `declocal`, `declocal_i`, `decrement`, and `decrement_i`.
* tests: `swf_approx` tests should be allowed to print NaNs.
* avm2: Implement `divide`.
* avm2: Implement `inclocal`, `inclocal_i`, `increment`, and `increment_i`.
* avm2: Implement `lshift`.
* Implement `modulo`.
* avm2: Implement `multiply` and `multiply_i` (no tests for the latter)
* avm2: Implement `negate` and `negate_i` (no tests for the latter)
* avm2: Implement `rshift`
* avm2: Implement `subtract` and `subtract_i` (the latter without tests)
* avm2: Implement `urshift`.
removeMovieClip should only function on objects within a certain
depth range, usually to prevent removing timeline clips. However,
this wasn't working properly in some cases because the depth was
being biased incorrectly (removeMovieClip never takes a depth
parameter, so we should not bias the depth).
same_item_push was added on nightly, but is currently throwing
a false negative. I added an allow for it, but this causes a
warning on stable for an unknown lints, so allow unknown lints for
now.
This has some particularly annoying consequences for initialization order: notably, we can't actually create any ES4 classes using the standard machinery until after the three objects I just mentioned get created. Ergo, we have to create them through lower-level means, handing prototypes around, and then initialize AVM2's system prototypes list for it.
When we start adding more system prototypes, we'll also have to fill the extras with blank objects and then slot them in as we create them.
We're about to massively change the initialization process, and we really don't want to create another situation where the player can get caught with it's pants down.
