[PATCH] i386: [APX] Add missing document for APX

[Hongyu Wang]

Hi,

The supported sub-features for APX was missing in option document and
target attribute section. Add those missing ones.

Ok for trunk?

gcc/ChangeLog:

	* config/i386/i386.opt: Add supported sub-features.
	* doc/extend.texi: Add description for target attribute.
