  [JSC] Add ALWAYS_INLINE_LAMBDA to some collectMatches lambdas

Reviewed by Justin Michaud.

This patch attaches always_inline attribute to some collectMatches lambdas.
We found that WSL gets regressed from 267071 at main. And we found that this slight
change made these critical functions non-inlined, causing severe regression.
Now because we already know that they should be inlined, this patch attaches
always_inline attribute to these lambdas. We add ALWAYS_INLINE_LAMBDA, which
is usable for lambda.
