Reworked how the compiler inserts the private broadcast calls.  This is done at the same time that the compiler puts local variables on the heap and relied on the removed assumption about the first definition for the broadcasts of arrays and domains.  Instead of looking at the first def, the compiler now looks for the first use or def in the initialization function of the module in which the global array or domain is declared and places the private broadcast after this use or def.

This fixes the 15 GASNet regressions.
