Support resolution of STT_GNU_IFUNC via breakpoints.
* breakpoint.c (print_it_typical): Support bp_gnu_ifunc_resolver and
bp_gnu_ifunc_resolver_return.
(bpstat_what): Rename parameter to bs_head, new variable bs, adjust
the loop. Support bp_gnu_ifunc_resolver and
bp_gnu_ifunc_resolver_return. New comment after the loop. New loop
for bp_gnu_ifunc_resolver and bp_gnu_ifunc_resolver_return
breakpoints.
(bptype_string, print_one_breakpoint_location): Support
bp_gnu_ifunc_resolver and bp_gnu_ifunc_resolver_return.
(user_settable_breakpoint): Return true also for
bp_gnu_ifunc_resolver.
(allocate_bp_location): Support bp_gnu_ifunc_resolver and
bp_gnu_ifunc_resolver_return.
(set_breakpoint_location_function): New parameter explicit_loc,
describe it. Call find_pc_partial_function_gnu_ifunc with new
variable IS_GNU_IFUNC and adjust the address for STT_GNU_IFUNC if
EXPLICIT_LOC is not set.
(set_raw_breakpoint): Set EXPLICIT_LOC for
set_breakpoint_location_function.
(clone_momentary_breakpoint): Use true for EXPLICIT_LOC of
set_breakpoint_location_function.
(mention): Support bp_gnu_ifunc_resolver and
bp_gnu_ifunc_resolver_return.
(add_location_to_breakpoint): Set EXPLICIT_LOC for
set_breakpoint_location_function.
(update_breakpoint_locations): Remove static.
(breakpoint_re_set_one): Support bp_gnu_ifunc_resolver and
bp_gnu_ifunc_resolver_return.
* breakpoint.h (enum bptype): New fields bp_gnu_ifunc_resolver and
bp_gnu_ifunc_resolver_return.
(update_breakpoint_locations): New declaration.
* elfread.c: Include gdbthread.h and regcache.h.
(elf_gnu_ifunc_resolver_stop, elf_gnu_ifunc_resolver_return_stop): New
functions.
(elf_gnu_ifunc_fns): Install them.
* minsyms.c (stub_gnu_ifunc_resolver_stop)
(stub_gnu_ifunc_resolver_return_stop): New functions.
(stub_gnu_ifunc_fns): Install them.
* symtab.h (struct gnu_ifunc_fns): New fields gnu_ifunc_resolver_stop
and gnu_ifunc_resolver_return_stop.
(gnu_ifunc_resolver_stop, gnu_ifunc_resolver_return_stop): New.
