Just to put in a counterpoint about libstdc++ testing (i agree
wholeheartedly with your general sentiment)

When I was working on load PRE, and when i work on aliasing issues,
the libstdc++ testsuite is often the only thing i can get to actually
fail when i break something :)

At least for me, I usually start with just various RUNTESTFLAGS that
only do the execute, tree-ssa, and libstdc++ tests, and if those are
clean, I go on to do a full test run.
The rest is just too expensive and not enough value in terms of found
bugs for the changes I make (the tree-ssa is really to ensure i
haven't regressed our tree optimizers, since if something is failing
there, it doesn't really matter about the rest of the results)
