bogus comparison operands to default to eq/oeq. Fix that, fix a couple of
tests that accidentally passed and test for bogus comparison opeartors
explicitly.

Upgrade syntax of tests using volatile instructions to use 'load volatile' instead of 'volatile load', which is archaic.2011-11-27T06:54:59ZChris Lattnersabre@nondot.org2011-11-27T06:54:59Zurn:sha1:d2bf432b2b6ba02e20958953a237213d48b00f20

Note that this change affects the existing non-atomic load and store
instructions; the parser now accepts both forms, and the change is noted
in the release notes.
