[PATCH] 64-bit support for Irix 6

[Kevin Buettner <kevinb@redhat.com>]

I've just committed the change below.

This change (along with some other changes coming soon) allow us to
debug 64-bit applications on Irix 6.X.  I've verified that this change
does not affect our ability to debug o32 and n32 applications.

	* config/mips/tm-irix6.h (MIPS_REGSIZE): Define to be 8.
	(REGISTER_VIRTUAL_TYPE): Some registers are now 64 bits wide.
