[RFA] BRANCH_COST (was Re: optimizing % CONST_INT)


While looking into this optimization issue on Sparc, I noticed that
fold-const.c provides the default for BRANCH_COST even though it
includes expr.h  This is totally unnecessary.

Ok for mainline and 3.1 branch?

	* fold-const.c (BRANCH_COST): Don't provide default here, expr.h
	does it.
