[commit: testsuite] master: Update some perf results for master (4afbacc)

I now get:

update the test so that GHC doesn't regress again)
     Expected    bytes allocated: 237077056 +/-10%
     Lower bound bytes allocated: 213369350
     Upper bound bytes allocated: 260784762
     Actual      bytes allocated: 101150736

Joachim: if you're building with DEBUG, that will adversely affect the 
performance tests, so you probably shouldn't run those.

Cheers,
Simon
