GDBARCH_BREAKPOINT_MANIPULATION and SET_GDBARCH_BREAKPOINT_MANIPULATION

Browse Source 
Many archs have only one kind of breakpoint, so their breakpoint_from_pc
implementations are quite similar.  This patch uses macro
GDBARCH_BREAKPOINT_MANIPULATION and SET_GDBARCH_BREAKPOINT_MANIPULATION
for breakpoint_from_pc, so that we can easily switch from
breakpoint_from_pc to breakpoint_kind_from_pc and sw_breakpoint_from_kind
later.
