- With avx512, passing a 512 bit vector in a union would be lowered incorrectly, causing an assert. #2362
- Codegen error in `if (try x = (true ? io::EOF? : 1))`, i.e. using if-try with a known Empty.
- Codegen error in `if (try x = (false ? io::EOF? : 1))`, i.e. using if-try with a CT known value.
- Reduce allocated Vmem for the compiler on 32 bit machines.
### Stdlib changes
- Add `==` to `Pair`, `Triple` and TzDateTime. Add print to `Pair` and `Triple`.
