Extended Description

Recent changes to AINL result in over-exuberant inlining directives
being inserted for user-defined functions.
E.g.:
sac2c SCSprf_reshape.sac -v1 -bopt:cyc:ainl:1 >crud.ainl1
sac@rattler:~/sac/testsuite/optimizations/constantfolding$ vi crud.ainl1
sac@rattler:~/sac/testsuite/optimizations/constantfolding$
sac@rattler:~/sac/testsuite/optimizations/constantfolding$ sac2c SCSprf_reshape.sac -v1 -bopt:cyc:cse:1 >crud.cse1
sac@rattler:~/sac/testsuite/optimizations/constantfolding$ vi crud.cse1
sac@rattler:~/sac/testsuite/optimizations/constantfolding$ diff crud.cse1 crud.ainl1

The new inline directives are for main() and id(), neither of which
should be inlined.

The above resulted in 91 grep failures for the CF unit test suite, far more
than we should see there.
