[JSC] Use StringSwitch with resolved rope strings in FTL
https://bugs.webkit.org/show_bug.cgi?id=322144
rdar://185366501
Reviewed by Yijia Huang.
FTL StringSwitch is really efficient for non atom strings, so let's use
it even for resolved rope strings. When we encounter a rope string, we
call a function and resolve them. If it is 8bit string, then returning a
data pointer so that we can use FTL StringSwitch with it.
