Instead of writing LLVM based rasterizer from scratch I tried experimenting
with lavapipe (gallium + llvmpipe for vulkan).

It can be built with 
meson configure -Dvulkan-drivers=swrast -Dgallium-drivers=swrast
set VK_ICD_FILENAMES to the lvp_icd.x86_64.json file and vulkaninfo should show

I tried running demos from
and all 7 runs fine with lavapipe.

shaders can be downloaded with export GALLIVM_DEBUG="ir"

This seems more promising than writing everything from scratch. This allows us
to focus core part of this bug.
