Thanks for the catches - fixed those up and committed in
c2e827ad5340fcf1735df6c77cb0311e56b985ef.

Also refactored some of the xfails along the lines of what Pedro
suggested in the one test case that had several similar failures
(gdb.base/label.exp). If/when we fix this in Clang it might be worth
refactoring into a common function (though I'm personally not very
vested in keeping the test suite usable with anything other than ToT
Clang - perhaps others are).
