Fix tests with Clang
Configuring GHC with --with-gcc=clang and then running the tests currently causes over 100 test failues. The vast majority are due to stderr differences due to Clang producing more warnings, specifically warning: argument unused during compilation.
The obvious solution would be to filter these out in the testsuite runner.
