target-ppc: add support for extended mtfsf/mtfsfi forms
Power ISA 2.05 adds support for extended mtfsf/mtfsfi form, with a new W field to select the upper part of the FPCSR register. For that the helper is changed to handle 64-bit input values and mask with up to 16 bits. The mtfsf/mtfsfi instructions do not have the W bit marked as invalid anymore. Instead this is checked in the helper, which therefore needs to access to the insns/insns_flags2. They are added in the DisasContext struct. Finally change all accesses to the opcode fields through extract helpers, prefixed with FP for consistency.
