[PATCH] D21448: Codegen: LICM Remove check for exactly 1 register def.

[Kyle Butt via llvm-commits]

Andrew, there's a test with a multiple register-def instruction in http://reviews.llvm.org/D21627.
The existing tests now cover 0-def instructions, as the double-indirection for the call gets hoisted to a single indirection.

I couldn't put the test in this revision, because memory-refs were not being propagated for the folded load in the instruction in question.
