exec.c: Relax restrictions on watchpoint length and alignment
The current implementation of watchpoints requires that they have a power of 2 length which is not greater than TARGET_PAGE_SIZE and that their address is a multiple of their length. Watchpoints on ARM don't fit these restrictions, so change the implementation so they can be relaxed.
