Rahul Joshi b7382ed3fe [MLIR] Extend Symbol verification to reject public symbol declarations.
- Extend the Symbol interface with `isDeclaration` to identify operations that declare
  a symbol as opposed to define it.
- Extend verification to disallow public declarations as per the discussion in
   https://llvm.discourse.group/t/rfc-symbol-definition-declaration-x-visibility-checks/2140
- Adopt the new interface for `FuncOp` and fix test and code to not have/create public
  function declarations.

Mehdi Amini d31c9e5a46 Change filecheck default to dump input on failure
Having the input dumped on failure seems like a better
default: I debugged FileCheck tests for a while without knowing
about this option, which really helps to understand failures.

Remove `-dump-input-on-failure` and the environment variable
FILECHECK_DUMP_INPUT_ON_FAILURE which are now obsolete.

River Riddle c774840492 [mlir] Update the CallGraph for nested symbol references, and simplify CallableOpInterface
Summary:
This enables tracking calls that cross symbol table boundaries. It also simplifies some of the implementation details of CallableOpInterface, i.e. there can only be one region within the callable operation.

Depends On D72042

River Riddle 8cb405a8be Add initial callgraph support.
Using the two call interfaces, CallOpInterface and CallableOpInterface, this change adds support for an initial multi-level CallGraph. This call graph builds a set of nodes for each callable region, and connects them via edges. An edge may be any of the following types:
* Abstract
  - An edge not produced by a call operation, used for connecting to internal nodes from external nodes.
* Call
  - A call edge is an edge defined via a call-like operation.
* Child
  - This is an artificial edge connecting nested callgraph nodes.

This callgraph will be used, and improved upon, to begin supporting more interesting interprocedural analyses and transformation. In a followup, this callgraph will be used to support more complex inlining support.
