    opts: Fix up -ffold-mem-offsets option keywords
    
    While the option was originally meant to be a Target option for a single
    target, it is an option for all targets, so should be Common rather than
    Target, and because it is an optimization option which could be different
    in between different LTO TUs, I've added Optimization keyword too.
    From what I can see, Bool is a non-documented non-existing keyword (at
    least, grep Bool *.awk shows nothing, so I've dropped that too.  Seems
    that the option parsing simply parses and ignores any non-existing keywords.
    
    Guess we should drop the Bool keywords from the gcc/config/riscv/riscv.opt
    file eventually, so that people don't copy this around.

            * common.opt (ffold-mem-offsets): Remove Target and Bool keywords, add
            Common and Optimization.
