[LLVMdev] Patch - Allow calls that return i8 or i16. On SPU.

[Kalle Raiskila]

hi,

either function call in this code makes llc (targeting SPU) assert:

declare i8 @return_i8()
declare i16 @return_i16()
define void @testfunc() {
   %rv1 = call i8 @return_i8()
   %rv2 = call i16 @return_i16()
   ret void
}

Attached is a patch to fix it, and remove some related redundant code.
Does this rather trivial fix warrant a test case?
