[PATCH] D14327: Add llvm.ldexp.* intrinsic, associated SDNode and library calls

[Nicolai Hähnle via llvm-commits]

Rebased on top of current trunk and addressed the various comments.

Since the TargetAction now defaults to Expand (which is actually LibCall
in disguise when available), I have removed several places where targets
redundantly set the action.
