[Sanitizers] Provide __internal_dup on Solaris
Both LLVM 8.0.0 and current trunk fail to link libclang_rt.ubsan.standalone-*.so
on Solaris 11/x86 with GCC 8.1.0:
Undefined first referenced
symbol in file
Scanning dependencies of target clang_rt.asan_cxx-x86_64
__sanitizer::internal_dup(int) ../sanitizer_common/CMakeFiles/RTSanitizerCommon.i386.dir/sanitizer_posix.cc.o
ld: fatal: symbol referencing errors
collect2: error: ld returned 1 exit status
make[2]: *** [projects/compiler-rt/lib/ubsan/CMakeFiles/clang_rt.ubsan_standalone-dynamic-i386.dir/build.make:233: lib/clang/9.0.0/lib/sunos/libclang_rt.ubsan_standalone-i386.so] Error 1
Fixed by providing an implementation, which allowed the i386-pc-solaris2.11 build
to finish.
