bors 06e88c306a Auto merge of #123125 - gurry:122561-bad-note-non-zero-loop-iters-2, r=estebank 
Remove suggestion about iteration count in coerce

Fixes #122561

The iteration count-centric suggestion was implemented in PR #100094, but it was based on the wrong assumption that the type mismatch error depends on the number of times the loop iterates. As it turns out, that is not true (see this comment for details: https://github.com/rust-lang/rust/pull/122679#issuecomment-2017432531)

This PR attempts to remedy the situation by changing the suggestion from the one centered on iteration count to a simple suggestion to add a return value.

It should also fix #100285 by simply making it redundant.

Gurinder Singh 6289ed8428 Remove note about iteration count in coerce 
and replace it with a simple note suggesting
returning a value.

The type mismatch error was never due to
how many times the loop iterates. It is more
because of the peculiar structure of what the for
loop desugars to. So the note talking about
iteration count didn't make sense

Steven Trotter 8a5245e7dd Refactored a few bits: 
- Firstly get all the information about generics matching out of the HIR
- Secondly the labelling for the function is more coherent now
- Lastly a few error message improvements

Steven Trotter df93364057 Added ability to report on generic argument mismatch better 
Needs some checking over and some tests have altered that need sanity checking, but overall this is starting to get somewhere now.
