Fix some profile consistency testcases

Information about profile mismatches is printed only with -details-blocks for some time.
I think it should be printed even with default to make it easier to spot when someone introduces
new transform that breaks the profile, but I will send separate RFC for that.

This patch enables details in all testcases that greps for Invalid sum.  There are 4 testcases
which fails:
  gcc.dg/tree-ssa/loop-ch-profile-1.c
     here the problem is that loop header dulication introduces loop invariant conditoinal that is later
     updated by tree-ssa-dom but dom does not take care of updating profile.
     Since loop-ch knows when it duplicates loop invariant, we may be able to get this right.

     The test is still useful since it tests that right after ch profile is consistent.
  gcc.dg/tree-prof/update-cunroll-2.c
     This is about profile updating code in duplicate_loop_body_to_header_edge being wrong when optimized
     out exit is not last in the loop.  In that case the probability of later exits needs to be accounted in.
     I will think about making this better - in general this does not seem to have easy solution, but for
     special case of chained tests we can definitely account for the later exits.
  gcc.dg/tree-ssa/update-unroll-1.c
     This fails after aprefetch invoked unrolling.  I did not look into details yet.
  gcc.dg/tree-prof/update-unroll-2.c
     This one seems similar as previous
I decided to xfail these tests and deal with them incrementally and filled in PR110590.
