  -----------
  [clang] convergent attribute does not require "all threads" (#135803)

The documentation for the `convergent` attribute claims that OpenCL and
CUDA require "all threads" in a group to call the same convergent
operation. This is true only for OpenCL, and in general, the
`convergent` attribute is used in LLVM IR on operations that have no
such constraint.
