Screenshot with and without bug

When Pillars of Eternity (GOG version 1.0.0.1, native Linux version) is runned with R600_DEBUG=llvm or any combination of it (R600_DEBUG="sb hyperz llvm" for example), the lightning is completely saturated to white. It works well with no R600_DEBUG or with R600_DEBUG="sb hyperz".

Included screenshots with the bug and without it. Since the bug doesn't happen using default settings, I put the severity as minor.

- GPU = Radeon HD 6850

- OS = Debian Sid

- Mesa version = 10.6~git1503070909.1ca39e~gd~u from Oibaf's PPA

There are many known issues with R600_DEBUG=llvm, and nobody's actively working on fixing it. Don't wait for this to get fixed, and don't use it for the time being.
