LOG: [AIX][clang][driver] Check the command string to the linker for exportlist opts
Summary:
Some of code in the patch are contributed by David Tenty.
1. We currently only check driver Wl options and don't check for the plain -b, -Xlinker or other options which get passed through to the linker when we decide whether to run llvm-nm --export-symbols, so we may run it in situations where we wouldn't if the user had used the equivalent -Wl, prefixed options. If we run the export list utility when the user has specified an export list, we could export more symbols than they intended.
2. Add a new functionality to allow redirecting the stdin, stdout, stderr of individual Jobs, if redirects are set for the Job use them, otherwise fall back to the global Compilation redirects if any.
