[Bug fortran/38112] New: unneeded temporary

[jv244 at cam dot ac dot uk]

since b is an allocatable without the target attribute, there is no way it can
'alias' a. No need for a temp thus

SUBROUTINE S(a)
INTEGER, POINTER, DIMENSION(:) :: a
INTEGER, DIMENSION(:), ALLOCATABLE :: b
ALLOCATE(b(10))
b(a)=1
END SUBROUTINE S

gfortran -c -Warray-temporaries test.f90
test.f90:5.2:

b(a)=1
 1
Warning: Creating array temporary at (1)
