Enhance fixItRemove() to be a bit more careful about what whitespace it leaves around: if the thing it is removing has leading and trailing whitespace already, this nukes an extra space to avoid leaving double spaces or incorrectly indented results.
This includes an extra fix for looking off the start of a buffer, which extractText doesn't and can't handle.

Most tests were using %swift or similar substitutions, which did not
include the target triple and SDK. The driver was defaulting to the
host OS. Thus, we could not run the tests when the standard library was
not built for OS X.
