water111 7348e6a4ff [decompiler] Update vector ops, reduce casts (#3849)
Update the decompiler to use the new vf macros.

Also, fix a bunch of silly casting issues where accessing inline fields
with an offset of 0 would be better than a cast:

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...

water111 f3c63f26bb fix let* format, new on stack guessing case, type failure, handle casts (#1860)
Fixes https://github.com/open-goal/jak-project/issues/1821 by adding a
special case for `new` method calls where the argument with type
`symbol` is actually an address to uninitialized structure on the stack.

Fixes https://github.com/open-goal/jak-project/issues/1849 (or at least
the cause of the issue Vaser gave in chat, and one random one I found in
`debug-sphere`)

Fixes https://github.com/open-goal/jak-project/issues/1853

Fixes https://github.com/open-goal/jak-project/issues/1857 by moving the
cast into the cond if the body is a single form and the destination type
is a bitfield/enum which is likely to work well. Seems to work on the
examples we could find in jak 1 and jak 2.

Also fixes an issue with casts on the result of `handle->process` (a
common place to use casts)

the output of process->handle is a plain process. Most of the time, you
end up casting this to a more specific. If you add a cast on every use
of the variable, the decompiler will decide to change the type of that
variable to the more specific type, and this breaks the handle cast.

so previously it was impossible to get code like
```
    (let* ((s2-0 (the-as swingpole (handle->process (-> self control hack))))
           (gp-0 (-> s2-0 dir))
           )
```
But now it will work
