1a5bd88881 alternate implementation of previous commit
This strategy adds another field to the SwitchBr instruction,
which is the result of the CheckSwitchProngs instruction. The
type of the result is void, and is unused, except that the SwitchBr
instruction will not perform analysis if the CheckSwitchProngs
instruction did not pass analysis. This allows the CheckSwitchProngs
instruction to do implicit casting for its type checking, while
preventing duplicate compile error messages.

8c39cdc89f fix await on early return when return type is struct
previously, await on an early return would try to access the
destroyed coroutine frame; now it copies the result into a
temporary variable before destroying the coroutine frame

fd75e73ee9 add f16 type
Add support for half-precision floating point operations.

Introduce `__extendhfsf2` and `__truncsfhf2` in std/special/compiler_rt.

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.

eb6a8e6a3b fix f128 remainder division bug
The modulo operation computed rem(b+rem(a,b), b) which produces -1
for a=1 and b=2.

Switch to a - b * trunc(a/b) which produces the expected result, 1.

6edd81109d 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.

31aefa6a21 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`.
