[LLD][PPC] Implement R_PPC_ADDR32

[jackoalan]

Summary

PPC 32-bit absolute pointer relocation implementation

[ruiu]

I didn't realize that the previous patch included the implementation of ADDR32 relocation because the title of the patch only says that it implemented REL24 and RE32. Please remove ADDR32 implementation from the previous patch and add to this patch, and change the title of this patch "Implement R_PPC_ADDR32."

Commit R_PPC_ADDR32 implementation in tandem with test

[ruiu]

LGTM. Please go ahead and commit.
