[ASan][test] XFAIL global-overflow.cpp etc. on SPARC

[rorth]

When enabling ASan testing on SPARC as per PR #107405, two tests FAIL in similar ways as detailed in Issue #108194: at -O1 and above, one line of the stacktrace lacks the line number info, causing the tests to FAIL. I could trace this to clang generating incomplete line number info; g++ gets this right.

To avoid this, this patch XFAILs the affected tests on SPARC.

Tested on sparcv9-sun-solaris2.11.
