[PATCH] D16221: [mips] Promote SETCC operands to i64 for 64-bit ISAs.

vkalintiris added a dependency: D16220: [mips] Fix RetCC_MipsN to promote types smaller than i64 to GPR-width..
Herald added a subscriber: dsanders.

Other than the removal/modification of the relevant instructions/patterns,
we had to teach SimplifySetCC() about the folding of any (zext (trunc ...))
operand when comparing with a constant integer value.

Depends on D16220.
