Description:
------------
WASM (*.wasm) is the webassembly program. And it seems will be the future for at least it runs fine in modern browser environment.
I'm trying to run it by using `php -S 127.0.0.1:8000 -t .` , and local directory contains "main.html", "main.js", "main.wasm" (those generated by emcc which is a warm compiler). The script "main.js" (or maybe main.html) will load "main.wasm" somewhere. And the browser tells me under the console:

wasm streaming compile failed: TypeError: Failed to execute 'compile' on 'WebAssembly': Incorrect response MIME type. Expected 'application/wasm'.

It seems when sending "main.wasm", it didn't set the header `application/wasm`.
(I think PHP should take care of those modern features...)

Apparently, application/wasm has not yet been registered with
IANA[1].

We support .wasm in PHP 8.0 as part of the switch to mime-db.
