r300/compiler: Try to eliminate REPL_ALPHA instructions

Scalar instruction that need to write to the xyz components of a
register must reserve the RGB instruction slot for a REPL_ALPHA
instruction.  With this commit, the scheduler will attempt to free
the RGB slot by moving the write to the w component of a register.
