Make shift argument to eoshift0 and eoshift2 be of type index_type
Test case that requires 4 GB RAM that exercises eoshift0:
program main
implicit none
integer(1) :: line(2_8**31+10)
line = 42
line = eoshift(line, 2_8**31+7)
print *, line(1:4)
print *, line((ubound(line, 1, kind=8)-4):ubound(line, 1, kind=8))
end program main
Before patch:
❯ ./a.out
0 0 0 0
42 42 42 42 42
With patch:
❯ ./a.out
42 42 42 0
0 0 0 0 0
Regtested on x86_64-pc-linux-gnu.
