[Sdcc-user] space created for unused string constant

[Ralph Doncaster]

The following program allocates code space for the string, even though it's
only used at compile time by sizeof().

int main()
{
    return sizeof("hello");
}

Here's the asm:
;   ../strsiz.c:4: return sizeof("hello");
    mov dptr,#0x0006
;   ../strsiz.c:5: }
    ret
    .area CSEG    (CODE)
    .area CONST   (CODE)
    .area CONST   (CODE)
__str_0:
    .ascii "hello"
    .db 0x00

I tested with sdcc 4.0.3 #11846 and #11771.
