are current fixes for 48 bits sufficient to later extend it to 52

Hi,
Sorry about the delay, this got lost in the shuffle.
Yes, the existing mozjs fixes should work for 52-bit VA's as well. They
are basically limiting the addresses that the the tagged JS objects are
allocated at. This means that even if the addresses expand to 52-bit
VA's the objects will continue to be allocated below 47-bits.
(or that is the theory).
