Cleanup lapack.jl

[jakebolewski]

• remove error checking macros
• check for error's consistently
• try to adhere to some semblance of standard formatting

You're having too much fun with gesdd and gesvd. Or maybe not enough.

[jakebolewski]

@tkelman any clues as to these ENOSPC error's?

[tkelman]

docker quotas? ref travis-ci/travis-ci#5241, maybe try a branch build with group: edge to see if we pass there? how big are the temp files our tests create?

[jakebolewski]

I am going to merge as the appveyor failure is unrelated.

Nice job.
