Log Message:
-----------
DFG backwards propagation should update Int52Rep operands depending on
negative zero usage
https://bugs.webkit.org/show_bug.cgi?id=292197
rdar://150070561
Reviewed by Yusuke Suzuki.
DFG's backwards propagation phase can update `NodeBytecodeNeedsNegZero` during
analysis, meaning that we will need to recalculate the use kind of the operand
at that point based on the new value of the flag.
