breakpoints when the watchpoint goes out of scope. Save & restore
the current frame after checking watchpoints.

makes all local watchpoints go out of scope).
(bpstat_stop_status): Handle hardware watchpoints much like normal
watchpoints. Delete the watchpoint and watchpoint scope breakpoint
when the watchpoint goes out of scope. Remove and reinsert all
breakpoints before returning if we stopped when a hardware watchpoint

watching a local expression, build a scope breakpoint too.
(map_breakpoint_numbers): Also call given function for any
related breakpoints.
(disable_breakpoint): Never disable a scope breakpoint.

breakpoints, but recompute the watchpoint_scope breakpoint's
frame and address (if we have an associated scope breakpoint).
(read_memory_nobpt): Handle hardware watchpoints like normal
watchpoints. When necessary handle watchpoint_scope breakpoints.

* xcoffread.c (read_xcoff_symtab): Ignore symbols of class C_EXT,
smtyp XTY_LD, sclass XMC_DS (external data segment label). They
often have the same names as debug symbols for functions, and
confuse lookup_symbol().

REGISTER_RAW_SIZE (1).
Together these changes work around a bug in HP's compiler. Both
seem to be necessary.
