[X86] Add comments to the end of FMA3 instructions to make the operation clear
Summary:
There are 3 different operand orders for FMA instructions so figuring out the exact operation being performed requires a lot of thought.
This patch adds a comment to the end of the assembly line to print the exact operation.
I think I've got all the instructions in here except the ones with builtin rounding.
I didn't update all tests, but I assume we can get them as we regenerate tests in the future.
