Merge r292269 - AI should do int32 optimization in ValueRep
https://bugs.webkit.org/show_bug.cgi?id=238699
Reviewed by Saam Barati.
When constant folding an int52 into a ValueRep AI doesn't
do our normal int32 boxing optimization. I'm not sure if
it matters since I couldn't find a test but it probably
doesn't hurt.
