Simplify tilegx sysdeps folder

With tilepro support removal we can now simplify internal tile support by
moving the directory structure to avoid the unnecessary directory levels
in tile/tilegx both on generic and linux folders.

Checked with a build for tilegx-linux-gnu and tilegx-linux-gnu-32 with
and without the patch, there is no difference in generated binary with
a dissassemble.

	* stdlib/bug-getcontext.c (do_test): Remove tilepro mention in
	comment.
	* sysdeps/tile/preconfigure: Remove tilegx folder.
	* sysdeps/tile/tilegx/Implies: Move definitions to ...
