Bug 1892 – min and max work improperly for mixed-sign numbers

(From a post by bearophile.) void main() { int a = -10; uint b = 10; writefln( min(a, b) ); } prints 10 as per the infamous "uint rot" that transforms everything touched by uint an uint as well. Not sure what the right solution is - either (a) fix CommonType to yield no common type for int and uint, (b) fix CommonType to yield long for those two, (c) leverage the semantics of min to yield int whenever the min of an int an uint is taken, (d) something else?

Fixed in 2.012.
