The configure script still accepts "macosx" for backward compatibility,
but every other part of CompCert now uses "macos".

This commit enriches the IA32 port so that it supports x86 processors in 64-bit mode as well as in 32-bit mode, depending on the value of Archi.ptr64, which itself is set from the configuration model.
To activate x86-64 bit support, configure with "x86_64-linux".
Main steps:
- Enrich Op.v and Asm.v with 64-bit operations
- SelectLong: in 64-bit mode, use 64-bit operations directly; in 32-bit mode, fall back on the old implementation based on pairs of 32-bit integers
- Conventions1: support x86-64 ABI in addition to the 32-bit ABI.
- Add support for the new 64-bit operations everywhere.
- runtime/x86_64: implementation of the supporting library appropriate for x86 in 64-bit mode
To do:
- More optimizations are possible on 64-bit integer arithmetic operations.
- Could add new chunks to load, say, an unsigned byte into a 64-bit long
(currently we load as a 32-bit int then zero-extend).
- Implements the wrong ABI for struct passing.
