Need for GMP 5.0.5

I believe we will need a GMP 5.0.5 release.
(1) GMP 5.0.4 recognises AMD 11h processors as 10h (aka K10), then
making use of the LZCNT instruction. Unfortunately, 11h processors
while later than 10h processors, don't implement all K10
instructions, and also don't raise an illegal instruction trap. The
impact is the worst possible, crashes all over the place.
(2) GMP 5.0.4 fails to recognise newer Intel sandybridge processors due
to a typo of "coreisrb" for "coreisbr" in GMP's config.guess. The
impact is not too bad, just a build failure.
Any other urgent changes needed?
