[Bug fortran/34067] New: gfortran.dg/char_cshift_2.f90 fails with -O3 -funroll-loops fails on Intel Darwin

["dominiq at lps dot ens dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

With revision 130081 the following tests fail:

FAIL: gfortran.dg/char_cshift_2.f90  -O3 -fomit-frame-pointer -funroll-loops 
execution test
FAIL: gfortran.dg/char_cshift_2.f90  -O3 -fomit-frame-pointer
-funroll-all-loops -finline-functions  execution test
FAIL: gfortran.dg/char_eoshift_2.f90  -O3 -fomit-frame-pointer -funroll-loops 
execution test
FAIL: gfortran.dg/char_eoshift_2.f90  -O3 -fomit-frame-pointer
-funroll-all-loops -finline-functions  execution test
FAIL: gfortran.dg/char_eoshift_4.f90  -O3 -fomit-frame-pointer -funroll-loops 
execution test
FAIL: gfortran.dg/char_eoshift_4.f90  -O3 -fomit-frame-pointer
-funroll-all-loops -finline-functions  execution test

They passed with revision 130037. 

I have looked at char_cshift_2.f90. It fails on the fourth test (shift array of
kind=8) and the failure requires one of the test with shift2 or shift3 (if I
comment the two calls, the failure disappears).
