*	Implement -Wself-assign, which warns on code such as:	Chandler Carruth	2011-01-04	1	-0/+47
	int x = 42; x = x; // Warns here. The warning avoids macro expansions, templates, user-defined assignment operators, and volatile types, so false positives are expected to be low. The common (mis-)use of this code pattern is to silence unused variable warnings, but a more idiomatic way of doing that is '(void)x;'. A follow-up to this will add a note and fix-it hint suggesting this replacement in cases where the StmtExpr consists precisely of the self assignment. llvm-svn: 122804
