For ISD::RET, if # of operands >= 2, try selection the real data dep. operand
...
first before the chain.
e.g.
int X;
int foo(int x)
{
x += X + 37;
return x;
}
If chain operand is selected first, we would generate:
movl X, %eax
movl 4(%esp), %ecx
leal 37(%ecx,%eax), %eax
rather than
movl $37, %eax
addl 4(%esp), %eax
addl X, %eax
which does not require %ecx. (Due to ADD32rm not matching.)

Implement a little hack for parity with GCC on crafty. This speeds up
...
186.crafty by about 16% (from 15.109s to 13.045s) on my system.
This turns allocas with unions/casts into scalars. For example crafty has
something like this:
union doub {
unsigned short i[4];
long long d;
};
int f(long long a) {
return ((union doub){.d=a}).i[1];
}
Instead of generating loads and stores to an alloca, we now promote the
whole thing to a scalar long value.
This implements: Transforms/ScalarRepl/AggregatePromote.ll
