GC handle enumeration bug

[rcj1]

In the DAC we assume that there are as many handle tables per handle table bucket as heaps. However, during server GC the number of handle tables is equal to the number of processors, which may not match the number of heaps (for example with DATAS on). This leads to incomplete enumeration in the DAC (and cDAC).
