SIMD glitched on iPhone and crashes on iPad

In my emscripten + C + WebGL project with [cglm](https://github.com/recp/cglm/issues/312) doing vector math, enabling SIMD via `-msimd128` produces broken floats, resulting in warping of the texture on screen, but only on an iPhone SE, iOS 16.4.1. On an iPad 9th gen, iOS 16.3.1, the WebApp straight up refuses to launch with SIMD active.
Tested this behavior is browser independent, as both Safari and Edge are affected. According to https://webassembly.org/roadmap/, SIMD should work on these browsers.

Since I'm still preparing my WebApp and don't expect users, I have purposefully left the WebApp in this broken state via commit https://github.com/FrostKiwi/frostorama/commit/a065c5a7d62e3f89f2aed6a0e514134bd571cafe#diff-76ed074a9305c04054cdebb9e9aad2d818052b07091de1f20cad0bbac34ffb52. ~~You can test this out live (until I revert SIMD usage in a week) by going to https://frostkiwi.github.io/frostorama/ clicking on `Project image` and seeing the image glitch out, as opposed to having proper projection math applied on Android or a normal PC browser.~~ Reverted buggy simd again with https://github.com/FrostKiwi/frostorama/commit/c92cf22bfe58f2fec4dff4abab3412aa54574a2d

I have not yet tracked down the specific line responsible, but highly suspect the vector operations from this line up to line 50 https://github.com/FrostKiwi/frostorama/blob/a065c5a7d62e3f89f2aed6a0e514134bd571cafe/src/render_loop.c#L22 . There are calculations happening preparing a Fullscreen quad to raytrace and passing these floats to a WebGL shader. I suspect, that enabling SIMD makes these calculations become invalid on the iPhone.

I was looking forward to enabling SIMD, since https://github.com/recp/cglm is purposefully designed to have WASM SIMD functions. However, I will have to revert the use of SIMD, since it breaks on iOS.

Cross-posted this in the cglm repo as well, since I suspect the math issues influencing that library: https://github.com/recp/cglm/issues/312
