There are a few keywords like "pass" in HLSL that are actually case-insensitive for FXC. This can be disabled with strict mode, but even if you do that FXC will continue to give an error if you try to use them in identifiers (at all, with any casing). This changes the namer code to escape these keywords even if the casing is different. If you're wondering where I got the list from: I looked at the list of strings in D3DCompiler_47.dll.

Honestly I realized while almost done with this that maybe trying to put maintenance effort into FXC rather than DXC wouldn't be worth it, but OH WELL. Feel free to deny this PR if we don't want to add bugfixes for FXC.
