The same issue exists on 64-bit Solaris/SPARC:

+FAIL: gcc.dg/vect/vect-117.c -flto -ffat-lto-objects  scan-tree-dump-not
optimized "Invalid sum"
+FAIL: gcc.dg/vect/vect-117.c scan-tree-dump-not optimized "Invalid sum"

As said in the other PR, this is more for Honza who thought checking we do not
end with invalid profiles for all vect testcases is a good thing ;)

Btw, the wrong count pops up in DOM3:

t.c.203t.dom3:;;   Invalid sum of incoming counts 138435014 (estimated locally,
freq 3.0936), should be 134239200 (estimated locally, freq 2.)

so it seems to be a jump threading issue.  It's gone with -fno-thread-jumps.

Very likely a latent issue, but of course the change triggering this does
have an effect on jump threading.

Confirmed.
