  [PowerPC][AIX] 64-bit large code-model support for toc-data (#90619)

This patch adds support for toc-data for 64-bit large code-model on AIX.
The sequence ADDIStocHA8/ADDItocL8 is used to access the data directly
from the TOC.
When emitting the instruction ADDIStocHA8, we check if the symbol has
toc-data attribute before creating a toc entry for it. When emitting the
instruction ADDItocL8, we use the LA8 instruction to load the address.
