-libanalysis is not aggressively folding vector bitcasts.  For example, the
-constant expressions generated when compiling this code:
-
-union vec2d {
-    double e[2];
-    double v __attribute__((vector_size(16)));
-};
-typedef union vec2d vec2d;
-
-static vec2d a={{1,2}}, b={{3,4}};
-    
-vec2d foo () {
-    return (vec2d){ .v = a.v + b.v * (vec2d){{5,5}}.v };

 IPSCCP is propagating elements of first class aggregates, but is not propagating
 the entire aggregate itself.  This leads it to miss opportunities, for example
 in test/Transforms/SCCP/ipsccp-basic.ll:test5b.
