[JSC] Supports Type Reflection for `WebAssembly.Module.imports` and
`WebAssembly.Module.exports`
https://bugs.webkit.org/show_bug.cgi?id=277608
Reviewed by Yusuke Suzuki.
The current JSC implements part of the WebAssembly Type Reflection proposal[1].
It allows to get
type informations through methods like `WebAssembly.Memory.prototype.type()` and
`WebAssembly.Table.prototype.type()`.
The Type Reflection API should also add a new `type` field to the elements of
the arrays returned by
`WebAssembly.Module.imports` and `WebAssembly.Module.exports`[2]. However, this
feature is not
currently implemented in JSC. This feature has been implemented to V8[3] and
SpiderMonkey[4].
This patch implements Type Reflection for `WebAssembly.Module.imports` and
`WebAssembly.Module.exports`.
