This patch is the initial patch for support of the AIX extended vector ABI. The extended ABI treats vector registers V20-V31 as non-volatile and we add them as callee saved registers in this patch.

Summary:
On 32-bit PPC target[AIX and BE], when we convert an `i64` to `f32`, a `setcc` operand expansion is needed. The expansion will set the result type of expanded `setcc` operation based on if the subtarget use CRBits or not. If the subtarget does use the CRBits, like AIX and BE, then it will set the result type to `i1`, leading to an inconsistency with original `setcc` result type[i32].
And the reason why it crashed underneath is because we don't set result type of setcc consistent in those two places.
This patch fixes this problem by setting original setcc opnode result type also with `getSetCCResultType` interface.
