The passing of struct/union arguments by value implemented in the verified
part of CompCert is not compatible with the ARM, PowerPC and x86 ABI.
Here we enrich the StructReturn source-to-source emulation pass
so that it implements the calling conventions defined in these ABIs.
Plus: for x86, implement the returning of struct/union results by value
in a way compatible with the ABI.

The only platform where we have two variants is ARM, and it's easier
to share the callling convention code between the two than to maintain
both variants separately.

- 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.

- C function types and Cminor signatures annotated by calling conventions.
esp. vararg / not vararg
- Cshmgen: generate correct code for function call where there are
more arguments than listed in the function prototype. This is
still undefined behavior according to the formal semantics,
but correct code is generated.
- C2C, */PrintAsm.ml: remove "printf$iif" hack.
- powerpc/, checklink/: don't generate stubs for variadic functions.
