1454862 - GC optimizations for BigInt

Status: RESOLVED FIXED

(Core :: JavaScript: GC, enhancement, P2)

Description

[Robin Templeton [:terpri]]

BigInt should have better integration with the garbage collector; in particular, relocating BigInt cells for compacting GC should be supported. It might also be possible to allocate BigInt values in the nursery.

(this is an optimization on a feature that was not enabled in ff66 -> no action needed)
