gfortran.h (gfc_expr): Remove from_H, add "representation" struct.

* gfortran.h (gfc_expr): Remove from_H, add "representation"
struct.
* primary.c (match_hollerith_constant): Store the representation
of the Hollerith in representation, not in value.character.
* arith.c: Add dependency on target-memory.h.
(eval_intrinsic): Remove check for from_H.
(hollerith2representation): New function.
(gfc_hollerith2int): Determine value of the new constant.
(gfc_hollerith2real): Likewise.
(gfc_hollerith2complex): Likewise.
(gfc_hollerith2logical): Likewise.
(gfc_hollerith2character): Point both representation.string and
value.character.string at the value string.
* data.c (create_character_initializer): For BT_HOLLERITH
rvalues, get the value from the representation rather than
value.character.
* expr.c (free_expr0): Update handling of BT_HOLLERITH values
and values with representation.string.
(gfc_copy_expr): Likewise.
* intrinsic.c (do_simplify): Remove special treatement of
variables resulting from Hollerith constants.
* dump-parse-trees.c (gfc_show_expr): Update handling of
Holleriths.
* trans-const.c (gfc_conv_constant_to_tree): Replace from_H
check with check for representation.string; get Hollerith
representation from representation.string, not value.character.
* trans-expr.c (is_zero_initializer_p): Replace from_H check
with check for representation.string.
* trans-stmt.c (gfc_trans_integer_select): Use
gfc_conv_mpz_to_tree for case values, so as to avoid picking up
the memory representation if the case is given by a transfer
expression.
* target-memory.c (gfc_target_encode_expr): Use the known memory
representation rather than the value, if it exists.
(gfc_target_interpret_expr): Store the memory representation of
the interpreted expression as well as its value.
(interpret_integer): Move to gfc_interpret_integer, make
non-static.
(interpret_float): Move to gfc_interpret_float, make non-static.
(interpret_complex): Move to gfc_interpret_complex, make
non-static.
(interpret_logical): Move to gfc_interpret_logical, make
non-static.
(interpret_character): Move to gfc_interpret_character, make
non-static.
(interpret_derived): Move to gfc_interpret_derived, make
non-static.
* target-memory.h: Add prototypes for newly-exported
gfc_interpret_* functions.
