Add `__gnu_h2f_ieee` and `__gnu_f2h_ieee` as aliases that are used in
Windows builds.
The logic in std/special/compiler_rt/extendXfYf2.zig has been reworked
and can now operate on 16 bits floating point types.
`extendXfYf2()` and `truncXfYf2()` are marked `inline` to work around
a not entirely understood stack alignment issue on Windows when calling
the f16 versions of the builtins.

nullable pointers follow const-casting rules
...
any *T -> ?*T cast is allowed implicitly, even
when it occurs deep inside the type, and the cast
is a no-op at runtime.
in order to add this I had to make the comptime value
representation of nullable pointers the same as the
comptime value representation of normal pointers,
so that we don't have to do any recursive transformation
of values when doing this kind of cast.

fix structs that contain types which require comptime
...
Now, if a struct has any fields which require comptime,
such as `type`, then the struct is marked as requiring
comptime as well. Same goes for unions.
This means that a function will implicitly be called
at comptime if the return type is a struct which contains
a field of type `type`.

This will convert all & into *. Due to the syntax
ambiguity (which is why we are making this change),
even address-of & will turn into *, so you'll have
to manually fix thes instances. You will be guaranteed
to get compile errors for them - expected 'type', found 'foo'
