IDISA Bit-Block Operations

This class contains operations that treat the entire contents of a register as a single value.

bitblock::any(x)	returns true iff there is any nonzero bit in x
bitblock::all(x)	returns true iff there is no zero bit in x
bitblock::load_aligned(p)	load and return a bitblock value from an aligned location p
bitblock::load_unaligned(p)	load and return a bitblock value from an unaligned location p
bitblock::store_aligned(p, x)	store bitblock value x to an aligned location p
bitblock::store_unaligned(p, x)	store bitblock value x to an unaligned location p
