[PATCH] D76059: [mlir][vulkan-runner] Use C-compatible wrapper emission.

[Denis Khalikov via Phabricator via llvm-commits]

denis13 added a comment.

This patch eliminates `VulkanLaunchOpOperandAdaptor` and enables `emitCWrappers` while lowering to LLVM dialect. By doing this we follow the official guideline for calling convention https://mlir.llvm.org/docs/ConversionToLLVMDialect/#calling-convention.
`emitCWrappers` enables the following steps:

1. Declares a new function _mlir_ciface_vulkanLaunch where memref arguments are converted to pointer-to-struct and the remaining arguments are converted as usual.
2. Adds a body to the original function (making it non-external) that
  1. allocates a memref descriptor,
  2. populates it, and
  3. passes the pointer to it into the newly declared interface function
  4. collects the result of the call and returns it to the caller.
