Many of the FastUnwindTest.* tests FAIL on SPARC, both Solaris and Linux. The issue is that the fake stacks used in those tests don't match the requirements of the SPARC unwinder in sanitizer_stacktrace_sparc.cpp which has to look at the register window save area.
I'm disabling the failing tests.
Tested on sparcv9-sun-solaris2.11.
