I am even seeing almost 10% performance drop from GCC 7 to the trunk even. Even
at -O2. This is on an OcteonTX2:
-O2:
7.4.0:
2150.408184
trunk:
2032.971945
-O2 -fno-tree-vectorize:
trunk:
2028.648257
-O3:
7.4.0:
2207.640167
trunk:
2049.228275

For the original testcase, since GCC 13, ifcombine does not combine the ifs. I
have not looked into why though.
