IEEE 758 does not define a fixed rule for what NaN to return in
the case of a fused multiply-add of inf * 0 + NaN. Different
architectures thus do different things:
* some return the default NaN
* some return the input NaN
* Arm returns the default NaN if the input NaN is quiet,
and the input NaN if it is signalling
We want to make this logic be runtime selected rather than
hardcoded into the binary, because:
* this will let us have multiple targets in one QEMU binary
* the Arm FEAT_AFP architectural feature includes letting
the guest select a NaN propagation rule at runtime
In this commit we add an enum for the propagation rule, the field in
float_status, and the corresponding getters and setters. We change
pickNaNMulAdd to honour this, but because all targets still leave
this field at its default 0 value, the fallback logic will pick the
rule type with the old ifdef ladder.
Note that four architectures both use the muladd softfloat functions
and did not have a branch of the ifdef ladder to specify their
behaviour (and so were ending up with the "default" case, probably
wrongly): i386, HPPA, SH4 and Tricore. SH4 and Tricore both set
default_nan_mode, and so will never get into pickNaNMulAdd(). For
HPPA and i386 we retain the same behaviour as the old default-case,
which is to not ever return the default NaN. This might not be
correct but it is not a behaviour change.

If the target sets default_nan_mode then we're always going to return
the default NaN, and pickNaNMulAdd() no longer has any side effects.
For consistency with pickNaN(), check for default_nan_mode before
calling pickNaNMulAdd().
When we convert pickNaNMulAdd() to allow runtime selection of the NaN
propagation rule, this means we won't have to make the targets which
use default_nan_mode also set a propagation rule.
Since RiscV always uses default_nan_mode, this allows us to remove
its ifdef case from pickNaNMulAdd().

For IEEE fused multiply-add, the (0 * inf) + NaN case should raise
Invalid for the multiplication of 0 by infinity. Currently we handle
this in the per-architecture ifdef ladder in pickNaNMulAdd().
However, since this isn't really architecture specific we can hoist
it up to the generic code.
For the cases where the infzero test in pickNaNMulAdd was
returning 2, we can delete the check entirely and allow the
code to fall into the normal pick-a-NaN handling, because this
will return 2 anyway (input 'c' being the only NaN in this case).
For the cases where infzero was returning 3 to indicate "return
the default NaN", we must retain that "return 3".
For Arm, this looks like it might be a behaviour change because we
used to set float_flag_invalid | float_flag_invalid_imz only if C is
a quiet NaN. However, it is not, because Arm target code never looks
at float_flag_invalid_imz, and for the (0 * inf) + SNaN case we
already raised float_flag_invalid via the "abc_mask &
float_cmask_snan" check in pick_nan_muladd.
For any target architecture using the "default implementation" at the
bottom of the ifdef, this is a behaviour change but will be fixing a
bug (where we failed to raise the Invalid exception for (0 * inf +
QNaN). The architectures using the default case are:
* hppa
* i386
* sh4
* tricore
The x86, Tricore and SH4 CPU architecture manuals are clear that this
should have raised Invalid; HPPA is a bit vaguer but still seems
clear enough.

Define a separate trait for fields that also applies to classes that are

which has multiple uses:
- it makes it possible to access the parent struct's TYPE_* for types
that are defined in Rust code, and to avoid repeating it in every subclass
- implementors of ObjectType will be allowed to implement the IsA<> trait and
therefore to perform typesafe casts from one class to another.
- in the future, an ObjectType could be created with Foo::new() in a type-safe
manner, without having to pass a TYPE_* constant.

The default flash model of fmc_cs0 is "w25q01jvq" whose size is 128MB,
so set jedec_id 0xef4021.

The testcases for ASPEED SMC model were placed in aspeed_smc-test.c.
However, this test file only supports for ARM32. To support all ASPEED SOCs
such as AST2700 whose CPU architecture is aarch64, introduces a new
aspeed-smc-utils source file and move all common APIs and testcases
from aspeed_smc-test.c to aspeed-smc-utils.c.
Finally, users are able to re-used these testcase for AST2700 and future
ASPEED SOCs testing.
