*	[ConstantFolding] Fold undef for integer intrinsics	Nikita Popov	2019-01-11	1	-48/+24
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	This fixes https://bugs.llvm.org/show_bug.cgi?id=40110. This implements handling of undef operands for integer intrinsics in ConstantFolding, in particular for the bitcounting intrinsics (ctpop, cttz, ctlz), the with.overflow intrinsics, the saturating math intrinsics and the funnel shift intrinsics. The undef behavior follows what InstSimplify does for the general cas e of non-constant operands. For the bitcount intrinsics (where InstSimplify doesn't do undef handling -- there cannot be a combination of an undef + non-constant operand) I'm using a 0 result if the intrinsic is defined for zero and undef otherwise.

*	[ConstantFolding] Add support for saturating add/sub	Sanjay Patel	2018-11-20	1	-0/+111
	Support saturating add/sub in constant folding, based on the APInt methods introduced in D54332. Patch by: @nikic (Nikita Popov) Differential Revision: https://reviews.llvm.org/D54531 llvm-svn: 347328
