This patch enables support that the XL compiler had for AIX under -qdatalocal/-qdataimported.

We implement the -mtocdata/-mno-tocdata options on AIX for marking which global variables to assign/not assign the "toc-data" attribute. Global variables may be specified explicitly to be or not to be "toc-data" in comma-separated lists following -mtocdata=/-mno-tocdata=. All remaining global variables will follow the generic -mtocdata/-mno-tocdata option if present, or otherwise will follow the default -mno-tocdata behaviour. We filter unsupported types for toc-data and emit diagnostics if the corresponding global is explicitly user-specified as toc-data.
