1924166 - Refactor AllocSite::initialHeap to get straight from state to heap

Status: RESOLVED FIXED

(Core :: JavaScript: GC, enhancement, P3)

Description

[Matthew Gaudet (he/him) [:mgaudet]]

This patch, which should land soon, adjusts the definition of AllocSite::intitialHeap

It would be nice if we could "always get the initial heap from the state whatever the kind here,"

This lets us simplify the initialHeap() method to a single AND operation.
