Andreas Kling 69bae3fd9a LibJS: Prevent object shape transitions during runtime object buildup ...

While initialization common runtime objects like functions, prototypes,
etc, we don't really care about tracking transitions for each and every
property added to them.

This patch puts objects into a "disable transitions" mode while we call
initialize() on them. After that, adding more properties will cause new
transitions to be generated and added to the chain.

This gives a ~10% speed-up on test-js. :^)
