Fix documentation of the new parameters.
2010-03-10 Sebastian Pop <sebastian.pop@amd.com>
* doc/invoke.texi: Fix documentation of graphite-max-nb-scop-params,
graphite-max-bbs-per-function, and loop-block-tile-size.
* params.def (PARAM_GRAPHITE_MAX_NB_SCOP_PARAMS): Replace "maximal"
with "maximum".
(PARAM_GRAPHITE_MAX_BBS_PER_FUNCTION): Same.
