Sanjoy Das cdafd8490a Introduce deoptimization operand bundles 
Summary:
This change introduces the notion of "deoptimization" operand bundles.
LLVM can recognize and optimize these in more precise ways than it can a
generic "unknown" operand bundles.

The current form of this special recognition / optimization is an enum
entry in LLVMContext, a LangRef blurb and a verifier rule.  Over time we
will teach LLVM to do more aggressive optimization around deoptimization
operand bundles, exploiting known facts about kinds of state
deoptimization operand bundles are allowed to track.

This directory contains testcases that the verifier is supposed to detect as
malformed LLVM code.  Testcases for situations that the verifier incorrectly
identifies as malformed should go in the test/Assembler directory.
