Einstein Toolkit build failure related to McLachlan, vectorisation and Sign

[Ian Hinder]

The ET currently does not build. See http://git.barrywardell.net/EinsteinToolkitTestResults.git/blob/945320ed4e3864cc2e000204eacf77c7eecad8e3:/build.log. Build error is

/home/ianhin/Cactus/EinsteinToolkitTests/arrangements/McLachlan/ML_BSSN/src/ML_BSSN_RHS1.cc(648): error: argument of type "__m128d" is incompatible with parameter of type "double" ptrdiff_t dir1 = Sign(beta1L);

This happens in multiple thorns. This happened after a recent commit to Vectors: http://git.barrywardell.net/arrangements/LSUThorns/Vectors.git/commit/4b4418d0efb5b06784e89f617701c7b7cd5f6059.
