Zi Xuan Wu	b534db940c	[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.

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.
