so that DImode can be allocated to FP/vector registers in more
cases, and we can avoid direct move operations. If the register
needs reloading, prefer GPRs over FP/vector registers. In the
case of FPR vs. Altivec registers, prefer FPR registers unless we
have the ISA 3.0 reg+offset scalar instructions.

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.
