Bug 1528582 adds unoptimized WebIDLCast functions that root new BigInts to perform integer conversion. As an optimization, these functions should be updated to convert values to (u)int64 without GC allocation.

Blocks: js-bigint
Priority: -- → P2

Unnecessary GC allocations only take place when the input value is either a Boolean or a String value. And I'm not sure it's crucial to optimise for these two input kinds, because we should expect that most inputs are already BigInt values.
