[Patch, fortran, RFC] PR 40958 Reduce size of module files

[Thomas Koenig]

Hello world,

the testing of the test patch I submitted earlier (Thanks Salvatore and
Joost!) has shown a performance increase, so here is a formal
submission.  No test case because this patch is not supposed to
change anything, just make module reading a bit more efficient.

Regression-tested on x86_64-unknown-linux-gnu.  OK for trunk?
