Doc: Merge Alpha/VMS and IA-64/VMS options

Hi,

this patch merges Alpha/VMS and IA-64/VMS options as there is only one .opt for them, so there is no need to duplicate the doc.

It also documents -mpointer-size.

Tested by 'make info'

Ok for trunk ?

Tristan.

	* doc/invoke.texi (VMS Options): Merge Alpha/VMS and IA-64/VMS
	Options.  Mention -mpointer-size.
