This commit changes the second instruction used to retrieve a symbol on aix/ppc64 if it is in .data or .bss section. The previous version always retrieves the symbol address via a load on its TOC symbol. However, as the TOC is also in .data, the symbol's address is close enough to be fetched directly and the load instruction can be replaced by an addi.
