Add lowerbitsets flag to gold plugin and libLTO, and add disable-opt flag to
gold plugin. These flags can be used by the compiler driver to enable/disable
various parts of the compilation pipeline in cases where they are not needed.
In particular, this helps reduce link time in cases where the bit set lowering
pass is needed for control flow integrity, but the rest of LTO is not needed.
