libgo: avoid confusion in upcase_fields in mksysinfo.sh
The mksysinfo.sh script could get confused when there were multiple
types starting with the same name. I believe this is the underlying
cause of GCC PR 78172.
Also redirect a grep to /dev/null to avoid extraneous messages during
the build.

xtensa: Fix PR target/78118
It started failing after the following commit: 32e90dc6a0cda45 ("PR
rtl-optimization/61047").
The change that made xtensa backend go ICE looks completely unrelated,
and indeed, the issue is caused by the side effect of
compute_frame_size() function call hidden in the
INITIAL_ELIMINATION_OFFSET macro. This call updates the value of the
xtensa_current_frame_size static variable, used in "return" instruction
predicate. Prior to the change the value of xtensa_current_frame_size was
set to 0 after the end of epilogue generation, which enabled the "return"
instruction for the CALL0 ABI, but after the change the additional
INITIAL_ELIMINATION_OFFSET calls make xtensa_current_frame_size non-zero
and "return" pattern unavailable.
Get rid of the global xtensa_current_frame_size and
xtensa_callee_save_size variables by moving them into the
machine_function structure. Implement predicate for the "return" pattern
as a function. Don't communicate completion of epilogue generation
through zeroing of xtensa_current_frame_size, add explicit epilogue_done
variable to the machine_function structure. Don't update stack frame
layout after the completion of reload.

(add_ranges_num): Remove useless prototype. Don't multiply
by 2 * DWARF2_ADDR_SIZE. Add maybe_new_sec argument, adjust
for new fields added to dw_ranges struct.
(add_ranges): Add maybe_new_sec argument and pass it
through to add_ranges_num.
(note_rnglist_head): New function.
(add_ranges_by_labels): Pass true as maybe_new_sec to
add_ranges_num, call note_rnglist_head on the head of the list.
(output_ranges): Add function comment. Switch to
.debug_ranges section here and emit .Ldebug_ranges0 label.
(index_rnglists, output_rnglists): New functions.
(gen_subprogram_die): Formatting fixes.
(add_high_low_attributes): Don't divide offsets
by 2 * DWARF2_ADDR_SIZE. Call note_rnglist_head on the
first list element or when pointing into the middle of
a list. Pass true as second argument to add_ranges on the
first block fragment after cold/hot section switch.
(init_sections_and_labels): For -gdwarf-5 use .debug_rnglists
section instead of .debug_ranges. Initialize
ranges_base_label if -gdwarf-5 -gsplit-dwarf.
(dwarf2out_finish): For -gdwarf-5 -gsplit-dwarf call
index_rnglists and add DW_AT_rnglists_base attr. Don't switch
to dwarf_ranges_section here or emit .Ldebug_ranges0 label.
Call output_rnglists for -gdwarf-5.
(dwarf2out_c_finalize): Clear rnglist_idx.
