[JSC] Inline fast path of Unicode reading part in YarrJIT
https://bugs.webkit.org/show_bug.cgi?id=296211
rdar://156179713
Reviewed by Daniel Liu.
This patch inlines the fast path of unicode character reading in
YarrJIT. We identified that reading thunk is really hot since it is
called for each character, and inlining this is really helpful.
We should not entirely inline it. We should do it only for the fast
path.
