Update README_DEVELOPERS and references to --vex-guest-chase-thresh.

Add a hint about using lldb in README_DEVELOPERS and fix any old references
to --vex-guest-chase-thresh=0 to --vex-guest-chase=no (mirroring the change
in commit 56e04256a "Rationalise --vex-guest* flags in the new IRSB
construction framework".

    BBV vectors will be different than those generated by other tools.
    In practice this does not seem to affect the accuracy of the
