cca49663a5
The comment and code here seems to match getTypeForExtReturn. The history shows that at the time this code was added, similar code existed in SelectionDAGBuilder. SelectionDAGBuiler code has since been refactored into getTypeForExtReturn. This patch makes FastISel match SelectionDAGBuilder. The test changes are because X86 has customization of getTypeForExtReturn. So now we only extend returns to i8. Stumbled onto this difference by accident.
