The patch expands the existing 32-bit toc-data attribute support to 64-bit.
In both 32-bit and 64-bit it is supported for small code model only.

Summary:
This patch implements the backend implementation of adding global variables
directly to the table of contents (TOC), rather than adding the address of the
variable to the TOC.
Currently, this patch will look for the "toc-data" attribute on symbols in the
IR, and then add those symbols to the TOC.
ATM, this is implemented for 32 bit AIX.
