  Log Message:

  [LV] Skipping all debug instructions when native vplan is enabled (#77413)

The following internal error occurred when using native vplan to
vectorize the program with the debug info generation.

Assertion `!isa<DbgInfoIntrinsic>(CI) && "DbgInfoIntrinsic should have been dropped during VPlan construction"' failed.

This patch ignored all debug instructions to fix the error when native
vplan is enabled.
