[svn r253] Removed -inlineasm option. inline asm is now enabled by default unless the new -noasm option is passed. Tried adding a stack trace print when compiler crashes, not sure it's working though. Changed data layouts to match that of llvm-gcc. Fixed casting function pointers. Added support checks in AsmStatement.

char* toStringz (char[] s)
{
        if (s.ptr)
            if (! (s.length && s[$-1] is 0))
                   s = s ~ '\0';
        return s.ptr;
}
