float parsing: Add test for a fixed issue

[kaushalmodi]

Fixes #14407 .

This issue was fixed by #18139.

This command passes on my machine:

# cd to cloned Nim repo
testament r tests/errmsgs/treportunused.nim   

[kaushalmodi]

@Araq I see that the order of the Hints got shuffled up when I added that let block at the end. Is that shuffling expected? For that reason, the diff of the discard block is bigger than I expected. I expected only line number changes in there. But instead, I also had to paste the exact order of Hints that I saw when compiling that test locally.

The order of the Hints messages is still an issue. The changes in this test passed on most machines, but failed on:

The order of the Hints messages is still an issue

please open a separate issue to track that (and cross-link there); it's fixable using perhaps similar approach as I did in #13701 for sorting sigmatch errors

in the meantime you can use a different file for the test case as a workaround

Ok, I'll do that later today. Thanks.

or wait for #18336 to get merged, that way we don't have to add another file here

[kaushalmodi]

@timotheecour Looks like waiting for your PR merge is the only option 😃
