`clangtk` crashes at clang::StmtVisitorBase<llvm::make_const_ptr, (anonymous namespace)::StmtProfiler, void>::Visit(clang::Stmt const*)

[wierton]

The bug triggering program:

void a(void) {}
void b(void) {
  int c = 0, d = 0;
#pragma omp atomic capture
  {
    d = c;
    c = a();
  }
}

When attempting to compile it using clangtk with option -O0 -fopenmp-simd, clangtk crashes with below output log (verification link: https://gcc.godbolt.org/z/9TohYb7T6):

<source>:7:7: error: assigning to 'int' from incompatible type 'void'
    7 |     c = a();
      |       ^ ~~~
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
