Expect test failure for T8832 on 32bit (re #8832)

Signed-off-by: Herbert Valerio Riedel <hvr@gnu.org>
Update 32bit & 64bit performance numbers

Some numbers have decreased but the haddock numbers have generally
increased noticeable again (see also last update in 970e5d99fb658b73)

This updates all numbers I noticed in the "fast" test-mode, *except* for
the T9203 test-case on 32bit, which needs more investigation before
bumping due to its significant increase:

  bytes allocated value is too high:
      Expected    bytes allocated: 50000000 +/-5%
      Lower bound bytes allocated: 47500000
      Upper bound bytes allocated: 52500000
      Actual      bytes allocated: 85093548
  *** unexpected failure for T9203(normal)
