This patch improves ifcombine by doing two things. First tries to see
if the then and else are swapped and handles that case.
Just a few hours after I posted:

Could you check that your patch works on my testcases? (and then we can add
them to the testsuite and forget about my patch)
I must say I like Marcs patch more ...
I agree it is better. Though I don't have time to test my testcases
on your patch.
They won't work as is, because I just give up on bit tests in the inverted
case. I guess replacing invert_tree_comparison with
fold_build1(TRUTH_NOT_EXPR) at the beginning of the function might bring
the patches closer (Andrew's patch seems to do more than mine, though I
haven't studied it in details).
