We treated this g as a sibling call to f:
int f (int);
int g (void) { return f (1); }
but not this one:
struct s { int i; };
struct s f (int);
struct s g (void) { return f (1); }
We treated them both as sibcalls on x86 before the first patch for PR36326,
so I suppose this is a regression of sorts from 4.3.
The patch allows function returns to be local aggregate variables as well
as gimple registers.
