[PATCH] D12341: add unpredictable metadata type for control flow

[Krzysztof Parzyszek via llvm-commits]

LGTM.  I was thinking about having something like MD_prof_hw as the top-level metadata for all HW-specific profiling data, but if any further changes are needed, they can be done later.  However, if this metadata is later extended (for example, to have target/subtarget identification attached to it), would the IR compatibility be a concern?
