  Hi,
this patch fixes wrong compare in remap_params which triggers a wrong
code with my followup patch.  This needs backporting to gcc11 as well
which I plan to do tomorrow.

Bootstrapped/regtested x86_64-linux, comitted.

gcc/ChangeLog:

	* ipa-modref-tree.h (modref_tree::remap_params): Fix off-by-one error.
