fix incorrect union const value generation
...
closes #1381
The union was generated as a 3 byte struct when it needed to be
4 bytes so that the packed struct bitcast could work correctly.
Now it recognizes this situation and adds padding bytes to become
the correct size so that it can fit into an array.

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

any *T -> ?*T cast is allowed implicitly, even

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`.
