What version of clang and VS 2015 are you using? I've tried with clang-tidy
and your sources, and I'm not able to reproduce this.

Furthermore, I don't understand why clang is rejecting this macro
definition. Clang accepts this on Linux:
#define _mm256_set_m128i(/* __m128i */ hi, /* __m128i */ lo) \
  (a + b)
int main() {
  int a, b;
  _mm256_set_m128i(a, b);
}

There doesn't seem to be MS-specific behavior around '#define
foo(/*comment*/ argname)', so far as I can tell.
