[PowerPC] Remove some dead VSX v4f32 store patterns

Browse Source 
These patterns are dead (because v4f32 stores are currently promoted to v4i32
and stored using Altivec instructions), and also are likely not correct
(because they'd store the vector elements in the opposite order from that
assumed by the rest of the Altivec code).
