E0076 needs to be updated to new format

[sophiajt]

From: src/test/compile-fail/E0076.rs

Error E0076 needs a span_label, updating it from:

error[E0076]: SIMD vector should be homogeneous
  --> src/test/compile-fail/E0076.rs:14:1
   |
14 | struct Bad(u16, u32, u32); //~ ERROR E0076
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^

To:

error[E0076]: SIMD vector should be homogeneous
  --> src/test/compile-fail/E0076.rs:14:1
   |
14 | struct Bad(u16, u32, u32); //~ ERROR E0076
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^ SIMD elements must have the same type

Bonus: The span should focus on the arguments

error[E0076]: SIMD vector should be homogeneous
  --> src/test/compile-fail/E0076.rs:14:1
   |
14 | struct Bad(u16, u32, u32); //~ ERROR E0076
   |            ^^^^^^^^^^^^^ SIMD elements must have the same type

I have updated the message to show after span. All tests are passing.
Figuring out how to make span point to the parameters only. Any suggestion is welcome.

ps Running test-suite almost burned up the back of my laptop 😂

@abhiQmar - sadly, some of the bonuses don't have enough information in the compiler to be completed. I looked around and wasn't able to find an easy way to get this span information.

Please feel free to submit without the bonus and I'll close the bonus part as not easily possible for now.

@jonathandturner Thanks for your help on this. I have submitted without the bonus, please review.
