Commit 4ceecc820b7197c2f302aa235875eb6619a397c3 by flo [ConstraintElimination] Handle constraints with all zero var coeffs. Constraints where all variable coefficients are 0 do not add any useful information. When checking, we can check if they are always true/false.

Commit 4e5c0c2a63e2dff804a32b22d7d815a35a47c8d7 by flo [ConstraintElimination] Wrap dump() call in LLVM_DEBUG (NFC). ConstraintSystem::dump only generates output with -debug, but there's no need to call it without -debug.
