Chris Peterson 3193160487 Bug 1222887 - Suppress -Wunreachable-code warning in tools/power. r=njn ...

tools/power/rapl.cpp:844:5 [-Wunreachable-code] code will never be executed

clang reports a -Wunreachable-code warning for sigemptyset() because Darwin's sigemptyset() is a macro that always returns 0. Thus `if (sigemptyset(&sa.sa_mask) < 0)` is always false and `Abort("sigemptyset() failed")` is never called. Linux's sigemptyset() can return 0 or -1. The extra parens around (0) suppress the clang warning.
