If the flag '-m64' is used on a 32-bit architecture/machine having
int32_t set to 'long', then these int32_t are forced to 64-bit ...
So, ignore the effect of -m64 on these archs and ignore
'64-bit only' tests on them.

During the linearization of a function, returns are directly
linearized as phi-sources and the exit BB contains the
corresponding phi-node and the unique OP_RET.
There is also a kind of optimization that is done if there is
only a single a return statement and thus a single phi-source:
the phi-source and the phi-node is simply ignored and the
unique value is directly used by the OP_RET instruction.
While this optimization make sense it also has some cons:
- the phi-node and the phi-source are created anyway and will
need to be removed during cleanup.
- the corresponding optimization need to be done anyway during
simplification
- it's only a tiny special case which save very litte.
So, keep things simple and generic and leave this sort of
simplification for the cleanup/simplification phase.
