One ASan test currently XPASSes on Solaris:
AddressSanitizer-i386-sunos :: TestCases/Posix/no_asan_gen_globals.c
It was originally XFAILed in D88218 because Solaris ld, unlike GNU ld, doesn't
strip local labels. Since then, the integrated assembler has stopped emitting those
local labels, so the difference becomes moot and the XFAIL can go.
Tested on amd64-pc-solaris2.11 and x86_64-pc-linux-gnu.
