Kai Luo b9c3941cd6 [PowerPC] Generate inlined quadword lock free atomic operations via AtomicExpand 
This patch uses AtomicExpandPass to implement quadword lock free atomic operations. It adopts the method introduced in https://reviews.llvm.org/D47882, which expand atomic operations post RA to avoid spilling that might prevent LL/SC progress.
