Akira Hatanaka 6636922675 Fix bugs in lowering of FCOPYSIGN nodes.
- FCOPYSIGN nodes that have operands of different types were not handled.
- Different code was generated depending on the endianness of the target.

Additionally, code is added that emits INS and EXT instructions, if they are
supported by target (they are R2 instructions).
