Detect and disable -fstack-check on macOS 10.15 with Xcode 11

- On macOS 10.15 and Xcode 11 -fstack-check is enabled by default. This
  breaks SIMD alignment (and other alignment) as detailed here:
  https://forums.developer.apple.com/thread/121887 resulting in random
  segfaults from within Eigen.
- The underlying problem also exists with earlier OS versions running
  Xcode 11 if -fstack-check is explicitly enabled.
- This CL explicitly disables -fstack-check on affected versions of
  macOS 10.15 and Xcode 11.

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.
