Another update to document -mcall- and -mtraceback= options. Cleanup to
remove -mabi={no-,}spe from the RS/6000 and PowerPC section. And a trim
to the help text for -mblock-compare-* and -mstring-compare-inline-
limit so they are not excessively long. The complete description for
those is now in invoke.texi. This is the last piece for 85321.
Testing in progress on linux-ppc64le, ok for trunk if tests are ok?
Thanks,
Aaron
