  -----------
  [X86] Place data in large sections for large code model (#70265)

This allows better interoperability mixing small/medium/large code model
code since large code model data can be put into separate large
sections.

And respect large data threshold under large code model.
gcc also does this: https://gcc.gnu.org/onlinedocs/gcc/x86-Options.html.
