Reviewers: Kasper Lund, William Hesse, iposva, Description: Experimental: processor flags are not preserved across CFG edges targeting labeled basic blocks. Merge code may be generated at the block exit which could potentially destroy a value in the flags register.
This solution is to always materialize the flag result in a register. The generated code is known to be bad but (more) correct and will have to be fixed as a future change.
