[RFA] Fix wide char definitions in mips/iris5.h

[Neil Booth]

This patch has been tested by David Billinghurst on mips-sgi-irix6.5.
It eliminates 33 gcc testsuite failures with -mabi=64.

I would almost call it an obvious fix, but I'd like to apply it to the
branch too, so I'd like an official go ahead.

To recap, I noticed that the existing definitions cause wide characters to
occupy 8 bytes with -mabi=64, which causes lexer warnings and testsuite
failures.

Neil.
