Cherry-pick r240917. rdar://problem/47810465
DFG's doesGC() is incorrect about the SameValue node's behavior.
https://bugs.webkit.org/show_bug.cgi?id=194211
<rdar://problem/47608913>
Reviewed by Saam Barati.
Only the DoubleRepUse case is guaranteed to not GC. The other case may GC because
it calls operationSameValue() which may allocate memory for resolving ropes.
