The load issue is really the same as PR 25553 and this is target independent.

All P1 enhancements not targeted towards 4.1, moving to P5.

Another testcase which effects all targets:
int logic_func1(int b, int d) {
if (d< b) return b+3; else return d+3;
}
int logic_func2(int b, int d)
{
int a;
if (d< b) a = b; else a = d;
return a+3;
}

This is not related to range propagation. Removing dependency on 18373.

Here is a PPC32 example:
short b,d;
short logic_func1() {
if (d< b) return b; else return d;
}
We get:
lis r2,ha16(_b)
lis r9,ha16(_d)
lha r0,lo16(_b)(r2)
lha r2,lo16(_d)(

What really should happening is that we do a combine after we copy the BB for
returning (this will help
more than just this case).

ug. This bug falls between a number of stools.
1) on ppc-64 ints are returned correctly sign extended to 64 bits
2) the tree-ssa optimizers are blind to parameter marshalling, so the necessary
sign extension
