Handle very large exponents in parser1

Was not flipping to Double, and values 6e101 overflow a Float and
convert to +Infinity instead.  Add a test-case with this and other nasty
stuff to the parser tests.  Change compareDouble to handle NaN's & Infs'
& relative-error.

Updated GLMVA to have more fine grained canceling during cholesky decomp. This is to make canceling work in cases with very large number of categoricals. Previously, GLM would only check for cancellation before and after cholesky is computed, but not during cholesky itself, which can take very long time and use all of the cpus.

Also added reporting of the size of the largest categorical at glm start.
