David Sehr 693c37aa86 Two changes relevant to LEA and x32:
1) allows the use of RIP-relative addressing in 32-bit LEA instructions under
   x86-64 (ILP32 and LP64)
2) separates the size of address registers in 64-bit LEA instructions from
   control by ILP32/LP64.

; Use %rip-relative addressing even in static mode on x86-64, because
; it has a smaller encoding.
