Debug information for enumerator values

[Iain Buclaw]

I've implemented this in gdc.

https://github.com/D-Programming-GDC/GDC/commit/021dda8feaba282fec60600729ba8abc2c64cf81

enum enum_byte   : byte   { kE1, kE2, kE3 }
enum enum_ubyte  : ubyte  { kE1, kE2, kE3 }
enum enum_short  : short  { kE1, kE2, kE3 }
enum enum_ushort : ushort { kE1, kE2, kE3 }
enum enum_int    : int    { kE1, kE2, kE3 }
enum enum_uint   : uint   { kE1, kE2, kE3 }
enum enum_long   : long   { kE1, kE2, kE3 }
enum enum_ulong  : ulong  { kE1, kE2, kE3 }

void main()
{
   enum_byte var_byte;
   enum_ubyte var_ubyte;
   enum_short var_short;
   enum_ushort var_ushort;
   enum_int var_int;
   enum_uint var_uint;
   enum_long var_long;
   enum_ulong var_ulong;
}

(gdb) print var_byte
$1 = test.enum_byte.kE1

(gdb) print var_ubyte
$2 = test.enum_ubyte.kE1

(gdb) print var_short
$3 = test.enum_short.kE1

(gdb) print var_ushort
$4 = test.enum_ushort.kE1

(gdb) print var_int
$5 = test.enum_int.kE1

(gdb) print var_uint
$6 = test.enum_uint.kE1

(gdb) print var_long
$7 = test.enum_long.kE1

(gdb) print var_ulong
$8 = test.enum_ulong.kE1

(gdb) print (ulong)var_ulong
$9 = 0

(gdb) print (byte)'test.enum_uint.kE2'
$10 = 1 '\001'

(gdb) print ('test.enum_ulong')3
$11 = (test.enum_ulong.kE2 | test.enum_ulong.kE3)

(gdb) print ('test.enum_ulong')2
$12 = test.enum_ulong.kE3

(gdb) print ('test.enum_ulong')4
$13 = (unknown: 4)


What do you think?  Is <module>.<name>.<member> too verbose, or 
just right? :-)
