Saying these are regressions is weird, -flto has pretty much broken -g support
and lots of guality tests don't FAIL just because of being flagged as
UNSUPPORTED (as the tests conservatively assume some of the errors might be gdb
bugs).

And in case of
 FAIL: gcc.dg/guality/sra-1.c  -O2  line 43 a.j == 14
 FAIL: gcc.dg/guality/sra-1.c  -O3 -fomit-frame-pointer  line 43 a.j == 14
 FAIL: gcc.dg/guality/sra-1.c  -O3 -g  line 43 a.j == 14
 FAIL: gcc.dg/guality/sra-1.c  -Os  line 43 a.j == 14
+FAIL: gcc.dg/guality/sra-1.c  -O2 -flto -flto-partition=none  line 43 a.j ==
14
+FAIL: gcc.dg/guality/sra-1.c  -O2 -flto  line 43 a.j == 14

it is obviously a good thing that sra-1.c fails the same way with -flto as it
does without -flto, that means -flto is less buggier wrt. -g.

Indeed.  Also compare to -fwhole-file (non-LTO) guality.

With recent enough gdb(?) I only see

FAIL: gcc.dg/guality/vla-1.c  -Os  line 17 sizeof (a) == 6

on the 4.7 branch (no LTO fail).
