* treat "[var + rip]" in intel assembler mode as addr_pic_no_got on x86-64

Browse Source 
(mantis #22665)
  + support "[var wrt ..gotpcrel]" nasm/yasm syntax in intel assembler mode
    for GOT-relative accesses on x86-64, + give an error when trying to do
    this on win64 (it doesn't have a GOT)
  * moved code that give a warning when using GOT-relative accesses to
    static data on x86-64 from the AT&T reader to rax86 so it's also
    active for the Intel assembler reader
  + added warning when not using GOT-relative accesses (but plain
    RIP-relative instead) to global data on non-Win64 x86-64
