fortran: Add testcases for PR120152, PR120153 and PR120158

The following patch adds testcase coverage for the 3 recently fixed
libgfortran PRs.
On trunk before those fixes I'm getting with -m32
FAIL: gfortran.dg/pr120152_1.f90   -O0  (test for excess errors)
FAIL: gfortran.dg/pr120152_1.f90   -Os  (test for excess errors)
and with -m64
