[JSC] Add PromiseThen DFG node
https://bugs.webkit.org/show_bug.cgi?id=300672
rdar://162573148
Reviewed by Sosuke Suzuki.
Add DFG node `PromiseThen`, which corresponds to Promise.prototype.then.
This will be compiled into a succinct operation call. And we also offer
type information additionally to remove type checks against the result
of PromiseThen.
