On the frontend side, this patch recovers AIX static init implementation to use the linkage type and function names Clang chooses for sinit related function. On the backend side, this patch sets correct linkage and function names on aliases created for sinit/sterm functions. Differential Revision: https://reviews.llvm.org/D84534
