base: Extend AddrRange to support more flexible addressing

Previously an AddrRange could express interleaving using a number of
consecutive bits and in additional optionally a second number of
consecutive bits. The two sets of consecutive bits would be xored and
matched against a value to determine if an address is in the
AddrRange. For example:

sel[0] = a[8] ^ a[12]
sel[1] = a[9] ^ a[13]
where sel == intlvMatch

This change extends AddrRange to allow more flexible interleavings
with an abritary number of set of bits which do not need be
consecutive. For example:

sel[0] = a[8] ^ a[11] ^ a[13]
sel[1] = a[15] ^ a[17] ^ a[19]
where sel == intlvMatch
