There are several more that we could support here, but I didn't feel
like going down the rabbit-hole of figuring them out. In particular,
some of the Clang enum fields aren't specific enough for us, so we'll
have to switch on the target to figure out how to translate-c them. That
can be a future enhancement.
The old `CallingConvention` type is replaced with the new
`NewCallingConvention`. References to `NewCallingConvention` in the
compiler are updated accordingly. In addition, a few parts of the
standard library are updated to use the new type correctly.
This commit begins implementing accepted proposal #21209 by making
`std.builtin.CallingConvention` a tagged union.
The stage1 dance here is a little convoluted. This commit introduces the
new type as `NewCallingConvention`, keeping the old `CallingConvention`
around. The compiler uses `std.builtin.NewCallingConvention`
exclusively, but when fetching the type from `std` when running the
compiler (e.g. with `getBuiltinType`), the name `CallingConvention` is
used. This allows a prior build of Zig to be used to build this commit.
The next commit will update `zig1.wasm`, and then the compiler and
standard library can be updated to completely replace
`CallingConvention` with `NewCallingConvention`.
The second half of #21209 is to remove `@setAlignStack`, which will be
implemented in another commit after updating `zig1.wasm`.
* Adds new cpu architectures propeller1 and propeller2.
These cpu architectures allow targeting the Parallax Propeller 1 and Propeller 2, which are both very special microcontrollers with 512 registers and 8 cpu cores.
Resolves#21559
* Adds std.elf.EM.PROPELLER and std.elf.EM.PROPELLER2
* Fixes missing switch prongs in src/codegen/llvm.zig
* Fixes order in std.Target.Arch

In theory, this should work for v68+. In practice, it runs into an LLVM
assertion when using a `freeze` instruction on `f16` values, similar to the
issue we had for LoongArch.
Abi.android on its own is not enough to know whether soft float or hard float
should be used. In the C world, androideabi is typically used for the soft float
case, so let's go with that.
Note that Android doesn't have a hard float ABI, so no androideabihf.
Closes#21488.

Since we never hooked up the (experimental) DirectX LLVM backend, we've never
actually supported targeting DXIL in Zig. With Microsoft moving away from DXIL,
that seems very unlikely to change.
