variables whose address is taken.
- CminorSel, RTL: add "annot" instructions.
- CminorSel to Asm: use type "annot_arg" for arguments of "annot" instructions.
- AST, Events: simplify EF_annot because constants are now part of the arguments.
Implementation is not complete yet.

- Support single-precision floats as first-class values
- Introduce chunks Many32, Many64 and types Tany32, Tany64 to
support saving and restoring registers without knowing
the exact types (int/single/float) of their contents, just
their sizes.
- Memory model: generalize the opaque encoding of pointers to
apply to any value, not just pointers, if chunks Many32/Many64
are selected.
- More properties of FP arithmetic proved.

- added RTL type "Tsingle"
- ABI-compatible passing of single-precision floats on ARM and x86

1- new register allocator (+ live range splitting, spilling&reloading, etc)
based on a posteriori validation using the Rideau-Leroy algorithm
2- support for 64-bit integer arithmetic (type "long long").

- no more prediction of return addresses (Asmgenretaddr is gone)
- instead, punch a hole for the retaddr in Mach stack frame and
fill this hole with the return address in the Asmgen proof.

injections compose (Values, Memdata, Memory)
- Memory chunks: Mfloat64 now has alignment 8; introduced Mfloat64al32
that works like old Mfloat64 (i.e. has alignment 4); simplified
handling of memcpy builtin accordingly.

ia32: lift restriction that 1st arg of ops cannot be ECX

- In pointer values "Vptr b ofs", interpret "ofs" as an unsigned int.
(Fixes issue with wrong comparison of pointers across 0x8000_0000)
- Revised Stacking pass to not use negative SP offsets.
- Add pointer validity checks to Cminor ... Mach
to support the use of memory injections in Stacking.
- Cleaned up Stacklayout modules.
- IA32: improved code generation for Mgetparam.
- ARM: improved code generation for op-immediate instructions.

- Reload temporaries are marked as destroyed (set to Vundef) across
operations in the semantics of LTL, LTLin, Linear and Mach,
allowing Asmgen to reuse them.
- Added IA32 port.
- Cleaned up float conversions and axiomatization of floats.
