Investigate why enabling and disabling intrinsics has such a large impact on fuel usage

[jeffcharles]

I've observed that enabling JS intrinsics seems to increase fuel usage and disabling them seems to reduce fuel usage and sometimes by rather large amounts. This is unexpected because the runtime is created during pre-initialization so adding the intrinsics shouldn't affect fuel usage. We should figure out why that's happening and what we can do to mitigate those fuel differences.
