There is a WIP proposal to enable webassembly stack switching which have been
implemented in v8:

https://github.com/WebAssembly/js-promise-integration

It is not possible to switch stacks that contain JS frames so the Emscripten JS
trampolines that allow calling functions with the wrong number of arguments
don't work in this case. However, the js-promise-integration proposal requires
the [type reflection for Wasm/JS API](https://github.com/WebAssembly/js-types)
proposal, which allows us to actually count the number of arguments a function
expects.

For better compatibility with stack switching, this PR checks if type reflection
is available, and if so we use a switch block to decide the appropriate
signature. If type reflection is unavailable, we should use the current EMJS
trampoline.

We cache the function argument counts since when I didn't cache them performance
was negatively affected.

This feature is off by default via code but on by default via the CLI. The `.gitignore` file contains `*` which causes the entire directory to be ignored.

On a Python built in debug mode, Py_DECREF() now calls
_Py_NegativeRefcount() if the object is a dangling pointer to
deallocated memory: memory filled with 0xDD "dead byte" by the debug
hook on memory allocators. The fix is to check the reference count
*before* checking for _Py_IsImmortal().

Add test_decref_freed_object() to test_capi.test_misc.

display_header() logs an empty line and flush stdout.

Remove encoding workaround in display_header() since stdout error

These are the most popular specializations of `LOAD_ATTR` and `STORE_ATTR`
that weren't already viable uops:

* Split LOAD_ATTR_METHOD_WITH_VALUES
* Split LOAD_ATTR_METHOD_NO_DICT
* Split LOAD_ATTR_SLOT
* Split STORE_ATTR_SLOT
* Split STORE_ATTR_INSTANCE_VALUE

Also:

* Add `-v` flag to code generator which prints a list of non-viable uops
  (easter-egg: it can print execution counts -- see source)
* Double _Py_UOP_MAX_TRACE_LENGTH to 128
