I'm not worried about the cost, but I really don't think the backend
should be doing this. It introduces a behavioral dependency on the
current working directory inside codegen, which is a bad idea. 'llc
somepath/t.bc' should never behave differently from '(cd somepath &&
Also the commit doesn't have a test case, so it must not solve an
actual problem! :)
