  [PowerPC][GlobalMerge] Reduce TOC usage by merging internal and private global data

This patch aims to reduce TOC usage by merging internal and private global data.

Moreover, we also add the GlobalMerge pass within the PPCTargetMachine pipeline,
which is disabled by default. This transformation can be enabled by -ppc-global-merge.
