c2a87a05f1 [OpenCL] Emit enqueued block as kernel
In OpenCL the kernel function and non-kernel function has different calling conventions.
For certain targets they have different argument ABIs. Also kernels have special function
attributes and metadata for runtime to launch them.

The blocks passed to enqueue_kernel is supposed to be executed as kernels. As such,
the block invoke function should be emitted as kernel with proper calling convention and
argument ABI.

This patch emits enqueued block as kernel. If a block is both called directly and passed
to enqueue_kernel, separate functions will be generated.

369e85a900 [Dominators] Remove the NCA check
Summary:
This patch removes the `verifyNCD` check.

The reason for this is that the other checks are sufficient to prove or disprove correctness of any DominatorTree, and that `verifyNCD` doesn't provide (in my option) better error messages then the other ones.
Additionally, this should give a (small) improvement to the total verification time, as the check is O(n), and checking the sibling property takes O(n^3).

There were two copies of the logic needed to construct a line stats

aa4ea5fb45 [ubsan] Don't emit function signatures for non-static member functions
The function sanitizer only checks indirect calls through function
pointers. This excludes all non-static member functions (constructor
calls, calls through thunks, etc. all use a separate code path). Don't
emit function signatures for functions that won't be checked.

Apart from cutting down on code size, this should fix a regression on
Linux caused by r313096. For context, see the mailing list discussion:
