ScannerTest#testPerformance(): Improve failure reporting.
This test apparently sometimes fails to match "123 " against
the floatPattern constructed at runtime, but I can't reproduce and
can't see why it would. It might be related to an issue inside
ICU that only occurs a rare fraction of the time, or it might
be related to a nonstandard Locale. This CL adds more detail to
the failure case in order to narrow this down.
I've also slightly tweaked the initialization part of the test.
Bug: 150310094
Test: atest CtsLibcoreTestCases:org.apache.harmony.tests.java.util.ScannerTest#testPerformance
(takes about 15 seconds on a Pixel 2).
Test: To make sure that I didn't have a bug in my String.format(),
temporarily moved the initialization of String message
to in front of the try block and checked that the test
still passed (but then took 21sec, unsurprisingly).
