Previously only WalkerPasses had access to the `getPassRunner` and
`getPassOptions` methods. Move those methods to `Pass` so all passes can use
them. As a result, the `PassRunner` passed to `Pass::run` and
`Pass::runOnFunction` is no longer necessary, so remove it.
Also update `Pass::create` to return a unique_ptr, which is more efficient than
having it return a raw pointer only to have the `PassRunner` wrap that raw
pointer in a `unique_ptr`.
Delete the unused template `PassRunner::getLast()`, which looks like it was
intended to enable retrieving previous analyses and has been in the code base
since 2015 but is not implemented anywhere.

We can't disallow it, as its result is non-null which we can't spill to a local.
This may cause issues eventually in the combination of GC + flatten, but
I don't expect it to. If it does we may need to revisit.

Previously the signature collection mechanism responsible for
populating the type section with signatures used by instructions only
collected signatures from indirect call and block instructions. This
works as long as all other control flow constructs like ifs, loops,
and tries contain blocks with the same signature. But it is possible
to have an if with non-block children, and we would need to collect
its signature as well.

This adds support for the reference type proposal. This includes support
for all reference types (`anyref`, `funcref`(=`anyfunc`), and `nullref`)
and four new instructions: `ref.null`, `ref.is_null`, `ref.func`, and
new typed `select`. This also adds subtype relationship support between
reference types.
This does not include table instructions yet. This also does not include
wasm2js support.
Fixes #2444 and fixes #2447.

Adds the ability to create multivalue types from vectors of concrete value
types. All types are transparently interned, so their representation is still a
single uint32_t. Types can be extracted into vectors of their component parts,
and all the single value types expand into vectors containing themselves.
Multivalue types are not yet used in the IR, but their creation and inspection
functionality is exposed and tested in the C and JS APIs.
Also makes common type predicates methods of Type and improves the ergonomics of
type printing.

(#2242)
Main change here is in pass.h, everything else is changes to work with the new API.
The add("name") remains as before, while the weird variadic add(..) which constructed the pass now just gets a std::unique_ptr of a pass. This also makes the memory management internally fully automatic. And it makes it trivial to parallelize WalkerPass::run on parallel passes.
As a benefit, this allows removing a lot of code since in many cases there is no need to create a new pass runner, and running a pass can be just a single line.

- Reflected new renamed instruction names in code and tests:
- `get_local` -> `local.get`
- `set_local` -> `local.set`
- `tee_local` -> `local.tee`
- `get_global` -> `global.get`
- `set_global` -> `global.set`
- `current_memory` -> `memory.size`
- `grow_memory` -> `memory.grow`
- Removed APIs related to old instruction names in Binaryen.js and added
APIs with new names if they are missing.
- Renamed `typedef SortedVector LocalSet` to `SetsOfLocals` to prevent
name clashes.
- Resolved several TODO renaming items in wasm-binary.h:
- `TableSwitch` -> `BrTable`
- `I32ConvertI64` -> `I32WrapI64`
- `I64STruncI32` -> `I64SExtendI32`
- `I64UTruncI32` -> `I64UExtendI32`
- `F32ConvertF64` -> `F32DemoteI64`
- `F64ConvertF32` -> `F64PromoteF32`
- Renamed `BinaryenGetFeatures` and `BinaryenSetFeatures` to
`BinaryenModuleGetFeatures` and `BinaryenModuleSetFeatures` for
consistency.

Mass change to apply clang-format to everything. We are applying this in a PR by me so the (git) blame is all mine ;) but @aheejin did all the work to get clang-format set up and all the manual work to tidy up some things to make the output nicer in #2048
