Chris Lattner 549e190236 [PatternRewriter] Rename OwningRewritePatternList -> RewritePatternSet and insert -> add
This maintains the old name to have minimal source impact on downstream codes, and
does not do the huge mechanical patch.  I expect the huge mechanical patch to land
sometime this week, but we can keep around the old names for a couple weeks to reduce
impact on downstream projects.

Chris Lattner 6874726610 [PatternMatching] Add convenience insert method to OwningRewritePatternList. NFC.
This allows adding a C function pointer as a matchAndRewrite style pattern, which
is a very common case.  This adopts it in ExpandTanh to show how it reduces a level
of nesting.

We could allow C++ lambdas here, but that doesn't work as well with type inference
in the common case.  Instead of:

  patterns.insert(convertTanhOp);

you need to specify:

  patterns.insert<math::TanhOp>(convertTanhOp);

which is boilerplate'y.  Capturing state like this is very uncommon, so we choose
to require clients to define their own structs and use the non-convenience method
when they need to do so.

Chris Lattner 3a506b31a3 Change OwningRewritePatternList to carry an MLIRContext with it.
This updates the codebase to pass the context when creating an instance of
OwningRewritePatternList, and starts removing extraneous MLIRContext
parameters.  There are many many more to be removed.

Stephan Herhut 4348d8ab7f [mlir][math] Split off the math dialect.
This does not split transformations, yet. Those will be done as future clean ups.
