9afc4fe0e2 Sema: solve a false positive "depends on itself" 
This improves the ABI alignment resolution code.

This commit fully enables the MachO linker code in stage3. Note,
however, that there are still miscompilations in stage3.

ac954eb539 regalloc: ensure we only freeze/unfreeze at the outermost scope 
This prevents a nasty type of bugs where we accidentally unfreeze
a register that was frozen purposely in the outer scope, risking
accidental realloc of a taken register.

Fix CF flags spilling on aarch64 backend.

wasm: Store signed ints as two's complement 
When a signed integer is negative, the integer will be stored as a two's complement,
rather than its signed value. Instead, we verify the signed bits during arithmetic operations.
This fixes signed cases of `@mulWithOverflow`.

edb3adaa33 stage2,llvm: handle softfloats in @intToFloat and @floatToInt 
If the hw doesn't have support for exotic floating-point types such
as `f80`, we lower the call to a compiler-rt function call instead.

I've added a behavior test specifically targeting this use case which
now passes on `aarch64-macos`.

Additionally, this commit makes it possible to successfully build
stage3 on `aarch64-macos`. We can print the compiler's help message,
however, building with it needs a little bit more love still.

496eb69273 CI: add non-LLVM backends to the test matrix 
We can't yet run the behavior tests with stage3, but at least we can run
them with stage2, and we can use the proper test matrix.

This commit also adds use_llvm and ofmt to the zig build system.

44252f4d35 LLVM: fix C ABI for windows 
* sret logic needed a check for hasRuntimeBits()
 * lower f128 on windows targets with the "sse" class rather than
   "memory". For reference, clang emits a compile error when __float128
   is used with the MSVC ABI, saying that this type is not supported.
   The docs for the x64 calling convention have both of these sentences:
   - "Any argument that doesn't fit in 8 bytes, or isn't 1, 2, 4, or 8 bytes,
     must be passed by reference."
   - "All floating point operations are done using the 16 XMM registers."
 * For i128, however, it is clear that the Windows calling convention
   wants such an object to be passed by reference. I fixed the LLVM
   lowering for function parameters to make this work.
