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.

With my previous patch the compiler ICEs if you use --enable-checking=df.
This patch fixes it, by calling df_update_entry_exit_and_calls instead of
df_update_entry_block_defs and df_update_exit_block_uses.
