[JSC][GreedyRegAlloc] Don't skip TrySplit for grouped Tmps
https://bugs.webkit.org/show_bug.cgi?id=287999
rdar://144820673
Reviewed by Yusuke Suzuki.
We shouldn't skip the TrySplit stage if the Tmp is an eagerly
coalaseced Tmp. Instead, for those Tmps, we should always split
regardless of its live range size.
