bswap builtins: give semantics to them, support bswap64 on all targets
* Added semantic for byte swap builtins
The `__builtin_bswap`, `__builtin_bswap16`, `__builtin_bswap32`, `__builtin_bswap64` builtin function are now standard builtin functions with a defined semantics.
The semantics is given in terms of the decode/encode functions used for the memory model.
* Added bswap64 expansion to PowerPC 32 bits.
* Added bswap64 expansion for ARM.
