MaheshRavishankar a99e06aa86 [mlir][Linalg] Avoid generating illegal operations during elementwise fusion.
In some cases, fusion can produce illegal operations if after fusion
the range of some of the loops cannot be computed from shapes of its
operands. Check for this case and abort the fusion if this happens.

Krzysztof Drewniak 40aef79db0 [MLIR][GPU] Add debug output to enable dumping GPU assembly
- Set the DEBUG_TYPE of SerializeToBlob to serialize-to-blob
- Add debug output to print the assembly or PTX for GPU modules before
  they are assembled and linked

Note that, as SerializeToBlob is a superclass of SerializeToCubin and
SerializeToHsaco, --debug-only=serialize-to-blom will dump the
intermediate compiler result for both of these passes.

In addition, if LLVM options such as --stop-after are used to control
the GPU kernel compilation process, the debug output will contain the
appropriate intermediate IR.

Michael Kruse 616f77172f [OpenMPIRBuilder] Detect and fix ambiguous InsertPoints for createParallel.
When a Builder methods accepts multiple InsertPoints, when both point to
the same position, inserting instructions at one position will "move" the
other after the inserted position since the InsertPoint is pegged to the
instruction following the intended InsertPoint. For instance, when
creating a parallel region at Loc and passing the same position as AllocaIP,
creating instructions at Loc will "move" the AllocIP behind the Loc
position.

To avoid this ambiguity, add an assertion checking this condition and
fix the unittests.

In case of AllocaIP, an alternative solution could be to implicitly
split BasicBlock at InsertPoint, using the first as AllocaIP, the second
for inserting the instructions themselves. However, this solution is
specific to AllocaIP since AllocaIP will always have to be first. Hence,
this is an argument to generally handling ambiguous InsertPoints as API
sage error.

Stephan Herhut 6d45284618 [mlir][memref] Add better support for identity layouts in memref.collapse_shape canonicalizer
When computing the new type of a collapse_shape operation, we need to at least
take into account whether the type has an identity layout, in which case we can
easily support dynamic strides. Otherwise, the canonicalizer creates invalid

Prashant Kumar 770353cd94 [MLIR] The return type in the `computeSingleVarRepr` function is modified to include equality expressions.
Earlier `computeSingleVarRepr` was returning a pair of upper bound and
lower bound indices of the inequality contraints that can be expressed
as a floordiv of an affine function. The equality expression can also be
expressed as a floordiv but contains only one index and hence the `LocalRepr`
class is introduced to facilitate this.

River Riddle 7ceffae18c [mlir] Convert OpTrait::FunctionLike to FunctionOpInterface
This commit refactors the FunctionLike trait into an interface (FunctionOpInterface).
FunctionLike as it is today is already a pseudo-interface, with many users checking the
presence of the trait and then manually into functionality implemented in the
function_like_impl namespace. By transitioning to an interface, these accesses are much
cleaner (ideally with no direct calls to the impl namespace outside of the implementation
of the derived function operations, e.g. for parsing/printing utilities).

I've tried to maintain as much compatability with the current state as possible, while
also trying to clean up as much of the cruft as possible. The general migration plan for
current users of FunctionLike is as follows:

* function_like_impl -> function_interface_impl
Realistically most user calls should remove references to functions within this namespace
outside of a vary narrow set (e.g. parsing/printing utilities). Calls to the attribute name
accessors should be migrated to the `FunctionOpInterface::` equivalent, most everything
else should be updated to be driven through an instance of the interface.

* OpTrait::FunctionLike -> FunctionOpInterface
`hasTrait` checks will need to be moved to isa, along with the other various Trait vs
Interface API differences.

* populateFunctionLikeTypeConversionPattern -> populateFunctionOpInterfaceTypeConversionPattern

create invalid IR, as expand_shape cannot expand arbitrary dynamic
