  [PowerPC] Simplify implementation of atomis loads (#191044)

The code for atomic loads is verbose. There are 10 different operations
and 4 memory sizes to support, which means 40 pseudo instructions are
used, with all the details repeated. This PR changes the following:

- Use a loop over the operations and the sizes to create the pseudo
instruction
 - Adds the memory size as last operand to the pseudo instruction
- Updates the C++ code to take advantage of the memory size in the
pseudo instruction
