Does the error prevent QtCreator from starting?

According to https://bugs.archlinux.org/task/41886 and other similar reports, it could be a mesa issue.

You can also try to build without clang (USE=-clang) to check if the problem comes from qt-creator's clang engine or from mesa's llvm backend.

I believe I did remove the --clang and it still failed.

Try to run qt-creator from the command line with the `-noload all` option. This will temporarily disable all plugins. Some plugins use opengl, and I suspect one of them is causing the crash in mesa/llvm.
