Subject: Add floating point hardware checking for Intel on GNU compilers

When using the -check function (the default) it is enabled for Kinship
computation and LM/LMM up to individual SNP computation. This means
there can no longer be NaN values for matrices that are reused for every
SNP, but it is possible to have NaN for individual SNPs.

Fixes #161
