  1. rustbuild: Remove ThinLTO-related configuration

    This commit removes some ThinLTO/codegen unit cruft primarily only needed during
    the initial phase where we were adding ThinLTO support to rustc itself. The
    current bootstrap compiler knows about ThinLTO and has it enabled by default for
    multi-CGU builds which are also enabled by default. One CGU builds (aka
    disabling ThinLTO) can be achieved by configuring the number of codegen units to
    1 for a particular builds.
    
    This also changes the defaults for our dist builders to go back to multiple
    CGUs. Unfortunately we're seriously bleeding for cycle time on the bots right
    now so we need to recover any time we can.
