[Win32] Rework crash-report since r145389.
- lib/Driver/Driver.cpp, tools/driver/driver.cpp: Exit status should not be propagated, although clang driver should catch exceptions.
- test/Driver/crash-report.c: Add REQUIRES:shell for now.
FIXME: setenv should work also on Lit.InternalShellRunner.
- test/Driver/crash-report.c: Remove XFAIL.
Thanks to Chad, To point out the issue.
