[Bug fortran/38324] Wrong lbound given to allocatable components

AFAICT this pr is the cause of half of the failures of
gfortran.dg/alloc_comp_constructor_1.f90 on i686-apple-darwin9 with
-fdefault-integer-8:

The second half is due to 24 "builtin_free" in the "original" dump. This is the
cause of some failures of this test on powerpc-apple-darwin9 (-O0/1, I have
filled pr38347 against the middle-end for the ICE got with higher
optimizations).
