Zi Xuan Wu 7a2cb6f21d [PowerPC] Fix assert from machine verify pass that atomic pseudo expanding causes mismatched register class
For atomic value operand which less than 4 bytes need to be masked. 
And the related operation to calculate the newvalue can be done in 32 bit gprc. 
So just use gprc for mask and value calculation.
