[PATCH] opts: Remove AUTODETECT_VALUE usage.

[Martin Liška]

The patch is about using OPTION_SET_P instead of a default
option value set in common.opt.

Patch can bootstrap on x86_64-linux-gnu and survives regression tests.

Ready to be installed?
Thanks,
Martin

gcc/ChangeLog:

	* common.opt: Remove Init(2) for some options.
	* toplev.c (process_options): Do not use AUTODETECT_VALUE, but
	use rather OPTION_SET_P.
