* 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

Until we actually figure out a version range for this, we shouldn't classify
this as using semver. Doing so results in a panic when trying to access the
version range since it's not in fact a semver value.
Only targets for which we don't source CPU models/features from LLVM should use
the fallback prong in this switch. Also make it exhaustive to catch similar
mistakes in the future.
At bare minimum, the compiler expects std.Target.<arch>.cpu.generic to work for
any given architecture when generating the builtin module. So rather than try to
hack that into working when the affected modules are omitted, just actually keep
them.
This affected lanai and xcore.
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.
Based on:
* `include/elf/common.h` in binutils
* `include/uapi/linux/elf-em.h` in Linux
* https://www.sco.com/developers/gabi/latest/ch4.eheader.html
I opted to use the tag naming of binutils because it seems to be by far the most
complete and authoritative source at this point in time.
The compiler actually doesn't need any functional changes for this: Sema
does reification based on the tag indices of `std.builtin.Type` already!
So, no zig1.wasm update is necessary.
This change is necessary to disallow name clashes between fields and
decls on a type, which is a prerequisite of #9938.
It's entirely unclear whether this should map to POWERPC or POWERPCFP, and as I
can find no evidence of people producing PE files for PowerPC since Windows NT,
let's just not make a likely-wrong guess. We can revisit this if the need ever
actually arises.
All of these were mapping to types that are little endian. In fact, I can find
no evidence that either Windows or UEFI have ever been used on big endian
systems.
Some of this is arbitrary since spirv (as opposed to spirv32/spirv64) refers to
the version with logical memory layout, i.e. no 'real' pointers. This change at
least matches what clang does.
