fli cannot create raw hazards

[HamzaYusufJamal]

PR #322 implements hazard testing for all float instructions, but some instructions like fli cannot trigger certain types of hazards, leading to a false sub-100% coverage report. This issue serves to keep track of the required change for a fix.

It's ok that fli can't create raw hazards. Can you modify the coverpoint used for fli so you don't try to hit them?

This issue extends beyond fli, so we will need a lot of reviews of the testplans to make sure we check for the right hazard types. We are also not testing gpr hazards for any of the float instructions, which we should be doing. All of these are creating many false 100% reports. @coreyqh and I will work together on the review, and then I will need to make additional changes to testgen to account for the new coverpoints.
