The arm NEON comment was about FELightingNEON.cpp which was removed in
https://codereview.chromium.org/14262015 , with the other neon code then
being garbage-collected later in https://codereview.chromium.org/313303003

The file also contains a few source_sets with only header files.
Since header filesa aren't compiled by themselves, that doesn't make much sense,
so remove all these targets that didn't also contain cc files.
