6f0fb22723 Add static pass registration 
Add static pass registration and change mlir-opt to use it. Future work is needed to refactor the registration for PassManager usage.

Change build targets to alwayslink to enforce registration.

adbba70d82 Simplify FunctionPass to eliminate the CFGFunctionPass/MLFunctionPass 
distinction.  FunctionPasses can now choose to get called on all functions, or
have the driver split CFG/ML Functions up for them.  NFC.

cdb9551aba Move the GraphTraits implementations for CFGs out to their own header, 
consolidate the implementations in CFGFunctionViewGraph.cpp into it, and
implement the missing const specializations for functions.  NFC.

fb3116f59e Add PassResult and have passes return PassResult to indicate failure/success.

95f31d53d5 Add GraphTraits and DOTGraphTraits for CFGFunction in debug builds. 
Enable using GraphWriter to dump graphviz in debug mode (kept to debug builds completely as this is only for debugging). Add option to mlir-opt to print CFGFunction after every transform in debug mode.
