It fixes the first test not the second (comment #5)

The *.original dump shows ANNOTATE_EXPRs:
if (ANNOTATE_EXPR ) goto L.3;
i.0 = 0;
count.2 = 2;
while (1)
{
if (ANNOTATE_EXPR ) goto L.2;

Created attachment 41124

the second test program
This is another test which fails with all the optimizations directives (except
-Og).

I also get a wrong result if I compile the test with
-O1 -fno-auto-inc-dec -fno-branch-count-reg -fno-combine-stack-adjustments
-fno-compare-elim -fno-cprop-registers -fno-dce -fno-defer-pop
-fno-del

Compiling the code with -O1 gives
131076.000 6.
10.000 6.
131080.000 6.
and with -Os
4. 6.
10.0
