[JSC] Use Data Call IC in FTL
https://bugs.webkit.org/show_bug.cgi?id=276000
rdar://130766372
Reviewed by Yijia Huang.
This patch makes FTL always use Data IC for CallLinkInfo.
As a result, now all calls use Data IC (except for DirectCallLinkInfo).
In addition to simplify the implementation, it also unlocks CallLinkInfo's
upgradeIfPossible feature for all code.
