Sometimes when running tests that print user output during their execution this output can be printed on the same line as XCTest results output, either before or after the results string. Previously this showed as a test that never finished (pending) in then test explorer, but with the introduction of swiftlang#1505 tests that start but don't find any completion output are assumed to be crashed and marked as failed. This extra user output interleaved with XCTest output would cause false positives, leading users to believe that their test never completed (crashed) when really we just missed the success/failure message from XCTest due to overly strict parsing. Relax the XCTest output parsing regexes so that matched strings don't need to be at the start of a line.
