ManDude cd68cb671e deftype and defmethod syntax major changes (#3094)
Major change to how `deftype` shows up in our code:
- the decompiler will no longer emit the `offset-assert`,
`method-count-assert`, `size-assert` and `flag-assert` parameters. There
are extremely few cases where having this in the decompiled code is
helpful, as the types there come from `all-types` which already has
those parameters. This also doesn't break type consistency because:
  - the asserts aren't compared.
- the first step of the test uses `all-types`, which has the asserts,
which will throw an error if they're bad.
- the decompiler won't emit the `heap-base` parameter unless necessary
now.
- the decompiler will try its hardest to turn a fixed-offset field into
an `overlay-at` field. It falls back to the old offset if all else
fails.
- `overlay-at` now supports field "dereferencing" to specify the offset
that's within a field that's a structure, e.g.:
```lisp
(deftype foobar (structure)
  ((vec    vector  :inline)
   (flags  int32   :overlay-at (-> vec w))
   )
  )
```
in this structure, the offset of `flags` will be 12 because that is the
final offset of `vec`'s `w` field within this structure.
- **removed ID from all method declarations.** IDs are only ever
automatically assigned now. Fixes #3068.
- added an `:overlay` parameter to method declarations, in order to
declare a new method that goes on top of a previously-defined method.
Syntax is `:overlay <method-name>`. Please do not ever use this.
- added `state-methods` list parameter. This lets you quickly specify a
list of states to be put in the method table. Same syntax as the
`states` list parameter. The decompiler will try to put as many states
in this as it can without messing with the method ID order.

Also changes `defmethod` to make the first type definition (before the
arguments) optional. The type can now be inferred from the first
argument. Fixes #3093.

Hat Kid fc43870d85 decompiler: obj -> this, set-time! and time-elapsed? macros (#3026)
This renames the method object in `defmethod`s to `this` and adds
detection for the `set-time!` and `time-elapsed?` macros.

Definitely my biggest PR yet...

ManDude ff924f6b00 improve decomp of state handlers and art groups (#3014)
- state handlers that are not inlined lambdas have smarter type
checking, getting rid of 99.9% of the casts emitted (they were not
useful)
- art groups were not being properly linked to their "master" groups.
- `max` in `ja` in Jak 2 was not being detected.

Another huge PR...

water111 7d7625f4f8 [jak2] workaround for cutscene playing (#2131) 2023-01-16 13:37:29 -05:00
Hat Kid 459d83f755 decomp: tomb-* files, target-indax, grunt-mech, breakable-wall, pillar-collapse, mechtest-obs, ruins-obs (#2114)
Manual patches in:

- `tomb-boulder`: a few `ppointer->handle`s (I think) were not being
decompiled properly (all used in combination with `clone-anim-once`)
- `ruins-obs`, `pillar-collapse`: `art-joint-anim` casts
- `tomb-beetle`: commented out a call to `shadow-control-method-14` that
was crashing the game when spawning the beetles
- `grunt-mech`: commented out `(.mula.s)` instruction

Notes:
- `enemy-info`'s `idle-anim-script` is most likely a `(pointer
idle-control-frame)`, however, some `nav-enemy-info` labels set it to
`#f` (first encountered in `tomb-beetle`, but also present in `hal`,
`roboguard` and `metalkor-setup`), which crashes the decompiler. This
may become a problem in the future when we eventually get to these
files. For this PR, I made `tomb-beetle` decompile with
`idle-anim-script` set to `#f` and have not noticed any issues/crashes
with that.
- `tomb-boulder` compiles and doesn't crash, but when trying to play the
Daxter chase sequence, the boulder sometimes either spawns at the origin
or spawns in the correct place, but doesn't move.
