Validate failures

[Simon Marlow]

 From a validate run just now on x86_64/Linux:

Unexpected failures:
    perf/compiler          T3064 [stat not good enough] (normal)
    perf/compiler          T4801 [stat not good enough] (normal)
    perf/haddock           haddock.base [stat not good enough] (normal)
    perf/haddock           haddock.compiler [stat not good enoug(normal)
    rename/should_fail     rnfail055 [stderr mismatch] (normal)
    roles/should_fail      Roles12 [bad stderr] (normal)
    typecheck/should_fail  T3468 [stderr mismatch] (normal)

Several of these look similar:

=====> T3468(normal) 1758 of 3823 [0, 0, 0]

Actual stderr output differs from expected:
