Reduce C code size for bit syntax instructions

Bit syntax instructions never store their result in a Y register.

Therefore, change the bit syntax instructions to use 'x' as the
destination instead of 'd'. That will simplify the code that stores
the result, and will be a slight reduction in code size and execution
time.
