James Molloy	3c711cad2a	Don't create a MIN/MAX node if the underlying compare has more than one use. ... If the compare in a select pattern has another use then it can't be removed, so we'd just be creating repeated code if we created a min/max node.

James Molloy	a6f56a768b	Mark SMIN/SMAX/UMIN/UMAX nodes as legal and add patterns for them. ... The new [SU]{MIN,MAX} SDNodes can be lowered directly to instructions for most NEON datatypes - the big exclusion being v2i64. llvm-svn: 237455	2015-05-15 16:15:57 +00:00
