305516fcd3 Allow isolated regions to form isolated SSA name scopes in the printer. 
This will allow for naming values the same as existing SSA values for regions attached to operations that are isolated from above. This fits in with how the system already allows separate name scopes for sibling regions. This name shadowing can be enabled in the custom parser of operations by setting the 'enableNameShadowing' flag to true when calling 'parseRegion'.

%arg = constant 10 : i32
foo.op {
  %arg = constant 10 : i32
}

55f2e24ab3 Remove ops in regions/blocks from worklist when parent op is being removed via GreedyPatternRewriteDriver::replaceOp. 
This fixes a bug where ops inside the parent op are visited even though the parent op has been removed.

b5f8a4be27 Introduce parser library method to parse list of region arguments 
- introduce parseRegionArgumentList (similar to parseOperandList) to parse a
  list of region arguments with a delimiter
- allows defining custom parse for op's with multiple/variadic number of
  region arguments
- use this on the gpu.launch op (although the latter has a fixed number
  of region arguments)
- add a test dialect op to test region argument list parsing (with the
  no delimiter case)

6b436eacbc Merge TypeUtilities library into the IR library 
The TypeUtilities.{cpp,h}, currently living in {lib,include/mlir}/Support, do
not belong to the Support library.  Instead, they form a separate utility
library that depends on the IR library.  The operations it provides relate to
standard types (tensors, memrefs) as well as to operation manipulation, making
them a better fit for the main IR library.

dac75ae5ff Split test-specific passes out of mlir-opt 
Instead put their impl in test/lib and link them into mlir-test-opt
