[Sanitizers, CMake] Basic sanitizer Solaris support (PR 33274) Summary: This patch, on top of https://reviews.llvm.org/D40898, contains the build system changes necessary to enable the Solaris/x86 sanitizer port. The only issue of note is the libclang_rt.sancov_{begin, end} libraries: clang relies on the linker automatically defining __start_SECNAME and __stop_SECNAME labels for sections whose names are valid C identifiers. This is a GNU ld extension not present in the ELF gABI, also implemented by gold and lld, but not by Solaris ld. To work around this, I automatically link the sancov_{begin,end} libraries into every executable for now. There seems to be now way to build individual startup objects like crtbegin.o/crtend.o, so I've followed the lead of libclang_rt.asan-preinit which also contains just a single object.
