ISD::EXTRACT_VECTOR_ELT SimplifyDemandedBits Support
The attached WIP patch to add SimplifyDemandedBits support for
ISD::EXTRACT_VECTOR_ELT exposes issues in Hexagon:
Failing Tests (2):
LLVM :: CodeGen/Hexagon/vect/setcc-v2i32.ll
LLVM :: CodeGen/Hexagon/vect/zext-v4i1.ll
LLVM ERROR: Cannot select: t41: v4i16 = any_extend t31
t31: v4i1 = setcc t26, t48, seteq:ch
t26: v4i16,ch = load<(load 8 from %ir.a0, align 64)> t0, t2, undef:i32
t2: i32,ch = CopyFromReg t0, Register:i32 %1
t1: i32 = Register %1
t4: i32 = undef
t48: v4i16 = bitcast Constant:i64<0>
t47: i64 = Constant<0></pre>
