clang warnings with LTO

gcc 11.2.1

Looks like no one have been trying to compile clang using gcc and optimise it
using LTO. Just done that and LTO reported 550 [-Wmaybe-uninitialized] warnings
Summary stats of all warnings:

[tkloczko at barrel SPECS]$ cat clang.out  | grep -- -W | sed 's/.*\[//; s/\]//' |
sort | uniq -c | sort -nr
    550 -Wmaybe-uninitialized
     13 -Wuninitialized
      3 -Wfree-nonheap-object
      1 -Walloc-size-larger-than=

Full log of all warnings is in attachment.
