[PATCH] Introduce new .text.sorted.* sections.

[Martin Liška]

Hi.

Aim of the patch is to introduce a new .text subsection that
will be sorted by default. That can be leveraged in LTO where we
want to provide a specific sorting of symbols in a binary.

For more information about IPA reorder, please take a look:

Ready to be installed?
Thanks,
Martin
