Prompted by Eric's request for SPARC, I'm also updating Alpha and MIPS
options docs for recent changes.  Tested in an (unrelated)
i386-pc-solaris2.11 bootstrap and by inspection with info.

Installed on mainline as obvious.

	gcc:
	* doc/invoke.texi (DEC Alpha Options, -mcpu): native support isn't
	Linux/GNU-specific.
	(DEC Alpha Options, -mtune): Likewise.
	(MIPS Options, -march): native is supported on IRIX.
