[JSC] Use SwitchChar / SwitchImm without jump table in DFG
https://bugs.webkit.org/show_bug.cgi?id=294818
rdar://154047818
Reviewed by Yijia Huang.
Let's convert SwitchString to SwitchChar if possible in DFG / FTL.
And we can emit binary switch for these new ones when we are not able to
construct JumpTable because clause conditions are too sparse etc.
