I think we should have an option to turn off various "discards
qualifier" warnings (only for C), or to make them hard errors.
This patch adds new option, called -Wdiscarded-qualifiers (as
suggested in the BZ) for that.

Regtested/bootstrapped on x86_64-linux, ok for trunk?

	PR c/43245
	* doc/invoke.texi: Document -Wdiscarded-qualifiers.
c-family/
	* c.opt (Wdiscarded-qualifiers): Add.
c/
	* c-typeck.c (convert_for_assignment): Pass OPT_Wdiscarded_qualifiers
	instead of 0 to WARN_FOR_QUALIFIERS.
