Currently, the DWARF description does not specify the signedness of the
representation of enumeration types. This is a problem in some
contexts where DWARF consumers need to determine if value X is greater
than value Y.
For instance in Ada:
type Enum_Type is ( A, B, C, D);
for Enum_Type use (-1, 0, 1, 2);
type Rec_Type (E : Enum_Type) is record
when A .. B => null;
when others => B : Booleann;
end record;
The above can be described in DWARF the following way:
DW_TAG_enumeration_type(Enum_Type)
| DW_AT_byte_size: 1
DW_TAG_enumerator(A)
| DW_AT_const_value: -1
DW_TAG_enumerator(B)
| DW_AT_const_value: 0
DW_TAG_enumerator(C)
| DW_AT_const_value: 1
DW_TAG_enumerator(D)
| DW_AT_const_value: 2
DW_TAG_structure_type(Rec_Type)
DW_TAG_member(E)
| DW_AT_type: <Enum_Type>
DW_TAG_variant_part
| DW_AT_discr: <E>
DW_TAG_variant
| DW_AT_discr_list: DW_DSC_range 0x7f 0
DW_TAG_variant
| DW_TAG_member(b)
DWARF consumers need to know that enumerators (A, B, C and D) are signed
in order to determine the set of E values for which Rec_Type has a B
field. In practice, they need to know how to interpret the 0x7f LEB128
number above (-1, not 127).
When in non-strict DWARF mode, this patch adds a DW_AT_encoding
attribute to generated DW_TAG_enumeration_type DIEs to make this
signedness explicit.

In order to handle large character lengths on (L)LP64 targets, switch
the GFortran character length from an int to a size_t.
This is an ABI change, as procedures with character arguments take
hidden arguments with the character length.
I also changed the _size member in vtables from int to size_t, as
there were some cases where character lengths and sizes were
apparently mixed up and caused regressions otherwise. Although I
haven't tested, this might enable very large derived types as well.
Also, as there are some places in the frontend were negative character
lengths are used as special flag values, in the frontend the character
length is handled as a signed variable of the same size as a size_t,
although in the runtime library it really is size_t.
I haven't changed the character length variables for the co-array
intrinsics, as this is something that may need to be synchronized with
OpenCoarrays.
This is v3 of the patch. All the issues pointed out by FX's review of
v2 have been fixed. In particular, there are now new functions
gfc_mpz_get_hwi and gfc_mpz_set_hwi, similar to the GMP functions
mpz_get_si and mpz_set_si, except that they get/set a HOST_WIDE_INT
instead of a long value. Similarly, gfc_get_int_expr now takes a
HOST_WIDE_INT instead of a long, gfc_extract_long is replaced by
gfc_extract_hwi. Also, the preliminary work to handle
gfc_charlen_type_node being unsigned has been removed.
Regtested on x86_64-pc-linux-gnu.
