To test the speed of fmttable itself I split fmttable and main

just prototype it in the main module (no import), then compiled
them separately before linking. This should prevent any
possible inlining/purity cleverness. ~1s for ldmd2, ~2s for
dmd, which is business as normal.
dmd is being clever and spotting that fmttable is pure, it
would be good if ldc/gdc could spot this to.
If so, should explicitly marking fmttable as pure close the gap
for initial code?
