								 Bill Wendling | c6df9883da | Have the X86 back-end emit the alias instead of what's being aliased. In most cases, it's much nicer and more informative reading the alias.

								 Dan Gohman | 400f75cb5e | Fix SimplifyDemandedBits' AssertZext logic to demand all the bits. It needs to demand the high bits because it's asserting that they're zero.
