* There is no longer a need to explicitly remap function attrs.
- This removes a potentially expensive call from the destructor of Function.
- This will enable some interprocedural transformations to now run intraprocedurally.
- This wasn't scalable and forces dialect defined attributes to override
a virtual function.
* Replacing a function is now a trivial operation.
* This is a necessary first step to representing functions as operations.

* Use `cast` rather than `dyn_cast` to get an assertion failure rather than a segfault in case of a type mismatch.
* Use stream operators to `emitOpError`s.

The idea is to lower `gpu.launch` operations into `gpu.launch_func` operations by outlining the kernel body into a function, which is closer to the NVVM model.

This syntax removes boilerplate and verbose list of region arguments in the
header of the entry block. It groups operands into segments related to GPU
blocks, GPU threads as well as the operands that are forwarded to the kernel.
The two former segments are also used to give names to the region arguments
that are used for GPU blocks and threads inside the kernel body region.

Define a new dialect related to GPU kernels. Currently, it only contains a
single operation for launching a kernel on a three-dimensional grid of thread
blocks, following a model similar to that of CUDA. In particular, the body of
the kernel contains operations executed by each thread and uses region
arguments to accept thread and block identifiers (similar to how the loop body
region accepts the induction value).
