The pipe signal handler must be installed before any other handlers are registered. This is because the Unix RegisterHandlers function does not perform a sigaction() for SIGPIPE unless a one-shot handler is present, to allow long-lived processes (like lldb) to fully opt-out of llvm's SIGPIPE handling and ignore the signal safely. Fixes a bug introduced in D70277. Tested by running Nick's test case: % xcrun ./bin/clang -E -fno-integrated-cc1 x.c | tee foo.txt | head I verified that child cc1 process exits with IO_ERR, and that the parent recognizes the error code, exiting cleanly.
