Restore old names of comparison primops
In 6579a6c7 we removed existing comparison primops and introduced new ones returning Int# instead of Bool. This commit (and associated commits in array, base, dph, ghc-prim, integer-gmp, integer-simple, primitive, testsuite and template-haskell) restores old names of primops. This allows us to keep our API cleaner at the price of not having backwards compatibility. This patch also temporalily disables fix for #8317 (optimization of tagToEnum# at Core level). We need to fix #8326 first, otherwise our primops code will be very slow.
