update icon: llvm: Simplify plain icon

[Finii]

[why]
While the plain icon is plainer than the original icon, it is still quite complex with very thin strokes.

[how]
Just take the outermost outlines of the plain icon and crate a solid icon from it.

Note

This can be controversial.
For me the plain icon is not really plain, it has lots and lots of detail and consists of 2600 nodes:

The simple plain icon proposed here drops all the details and uses just the outline (260 nodes)

If one needs an icon with all the glory details the -original should be a good fit, the plain should be a simple(r) version, I believe. But anyhow, this is very opinionated and I do not want to mess with your ideas here. For a small text icon the current plain icon is far too complex and all the small detail hairlines can not be seen anyhow.

@Snailedlt as per ryanoasis/nerd-fonts#1691 (comment)

Hmm, hand-remove the gaps in the tail, that is an obvious artifact of the fill related broken outline in the original svg.
Force push.

[Snailedlt]

hmmm, I don't agree with this one. While I agree that the icon could benefit from some simplification I think going all black is too much simplification, making it less recognizable... but let's see what the other maintainers think too :)

Edit:

Good that you fixed the artifact though. That should probably be fixed in the original icon too.

Some context: The original icon is made by converting a png to svg with inkscape. The process is not ideal so there are a few artifacts. I think it could be improved upon now though, since I know there are better png to svg converters out there now than when we made this icon :)

hmmm, I don't agree with this one

😆

As I said, controversial (see image below).

For me, as "in a font" the current plain one is just too intricate. Have a look at it sized down:

But that is just for ME and font usage, which might or might not be important for you.
Just wanted to share this icon version with you.

[Snailedlt]

I agree it looks better in the font, but in larger sizes it looks significantly worse. Perhaps we could find some middle ground?
One way would be to roughly inverse the current plain version, and remove some of the detailing lines.

I'm thinking something like this (just with transparent lines instead of white ones):

@Finii
Here's a suggestion. Though it should be optimized more, because it's very large (80Kb).
I optimized it using SVGOMG, but it should probably be optimized more by reducing the amount of nodes in the path.

Sidenote: The old plain version can still be used as a line version instead :)
