ambiguous operator *= with hipFloatComplex

Tested with ROCm 5.2.

HIP version: 5.2.21151-afdc89f8
AMD clang version 14.0.0 (https://github.com/RadeonOpenCompute/llvm-project roc-5.2.0 22204 50d6d5d5b608d2abd6af44314abc6ad20036af3b)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /opt/rocm-5.2.0/llvm/bin

Reproducer:

// File complex.hip.cc
#include <hip/hip_runtime.h>
#include <hip/hip_complex.h>

__global__
void kernel( hipFloatComplex x, hipFloatComplex y )
{
    // This next line produces a compile error,
    // because hipFloatComplex is simply a typedef of HIP_vector_type.
    x *= y;

    // This works.
    x = x * y;
}

void driver( hipFloatComplex x, hipFloatComplex y, hipStream_t stream )
{
    hipLaunchKernelGGL( kernel, dim3(1), dim3(1), 0, stream, x, y );
}

int main( int argc, char** argv )
{
    hipFloatComplex x, y;
    hipStream_t stream;
    driver( x, y, stream );
    return 0;
}
