forwprop: bit_field_ref(constructor)

2012-09-22 Thread Marc Glisse
Hello, this patch lets forwprop fold bit_field_refs of constructors. It is particularly useful in forwprop4, which happens after the pass that lowers unsupported vector operations. Indeed, that pass keeps breaking vectors into pieces and reconstructing them for each operation, which is a waste
