  Log Message:
  -----------
  Initialize unsigned integer when declared (#81894)

Initialize ModOpcode directly before the loop execution to silence
static analyzer warnings about the usage of an uninitialized variable.

This leads to a redundant assignment of ElV2F16 inside the first loop
execution, but also avoids superfluous emptiness checks of EltsV2F16
after the first execution of the loop.
