[Bug fortran/38718] New: some simplifiers for elemental intrinsics missing; required for init expressions

The elemental intrinsic functions listed below lack simplifiers to make them
usable in initialization expressions:
DREAL (GNU extension)
ERFC_SCALED (F2008)
IS_IOSTAT_END (F2003)
IS_IOSTAT_EOR (F2003)
ISNAN (GNU extension)
LSHIFT (GNU extension)
MERGE (F95)
RSHIFT (GNU extension)
Probably only ERFC_SCALED and MERGE are of real significance.
Valid code example that's currently rejected:
$> cat merge.f90
INTEGER, PARAMETER :: k = selected_real_kind (precision (0.0_8) + 1)
INTEGER, PARAMETER :: nbytes = MERGE(48, 32, k == 16)
INTEGER, PARAMETER :: n = nbytes / KIND(n) + 1
END
merge.f90:3.38:
INTEGER, PARAMETER :: n = nbytes / KIND(n) + 1
1
Error: Function 'nbytes' in initialization expression at (1) must be an
intrinsic or a specification function
