Subject: [PATCH 1/7] [clang][CodeGen] Omit pre-opt link when post-opt link
requested
Currently, when the -relink-builtin-bitcodes-postop option is used
we link builtin bitcodes twice: once before optimization, and again
after optimization.
With this change, we omit the pre-opt linking when the option is
set, and we rename the option to the following:
-link-builtin-bitcodes-postopt
