Marcel Koester 8e640ca5a8 [mlir] Fixed warning related to unused variable in Liveness. 
The latest changes of the Liveness analysis caused a warning related to an
unused variable. This commit solves this warning.

Marcel Koester c79227cabb [mlir] Extended Liveness analysis to support nested regions. 
The current Liveness analysis does not support operations with nested regions.
This causes issues when querying liveness information about blocks nested within
operations. Furthermore, the live-in and live-out sets are not computed properly
in these cases.

Mehdi Amini 308571074c Mass update the MLIR license header to mention "Part of the LLVM project" 
This is an artifact from merging MLIR into LLVM, the file headers are
now aligned with the rest of the project.

River Riddle 2bdf33cc4c [mlir] NFC: Remove Value::operator* and Value::operator-> now that Value is properly value-typed. 
Summary: These were temporary methods used to simplify the transition.

River Riddle e62a69561f NFC: Replace ValuePtr with Value and remove it now that Value is value-typed. 
ValuePtr was a temporary typedef during the transition to a value-typed Value.

River Riddle ab46543ceb Resubmit: ReImplement the Value classes as value-typed objects wrapping an internal pointer storage. 
This will enable future commits to reimplement the internal implementation of OpResult without needing to change all of the existing users. This is part of a chain of commits optimizing the size of operation results.

River Riddle 35807bc4c5 NFC: Introduce new ValuePtr/ValueRef typedefs to simplify the transition to Value being value-typed. 
This is an initial step to refactoring the representation of OpResult as proposed in: https://groups.google.com/a/tensorflow.org/g/mlir/c/XXzzKhqqF_0/m/v6bKb08WCgAJ

This change will make it much simpler to incrementally transition all of the existing code to use value-typed semantics.
