c02d98e335 Expand case for 64b Legalize, even though no one should end up using this
(itanium supports bswap natively, alpha should custom lower it using the
VAX floating point swapload, ha ha).

69a889eb35 Fix a nasty latent bug in the legalizer that was triggered by my patch
last night, breaking crafty and twolf.  Make sure that the newly found
legal nodes are themselves not re-legalized until the next iteration.

Also, since this functionality exists now, we can reduce number of legalizer
iterations by depending on this behavior instead of having to misuse 'do
another iteration' to get the same effect.
