[PATCH] 64-bit support for Irix 6

- Subject: [PATCH] 64-bit support for Irix 6
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.
