cefcf39faa compiler_rt: strong linkage when compiling to .c 
This works around a problem that started happening with LLD around
version 18.1.8:

```
lld-link: error: duplicate symbol: .weak.__nexf2.default
>>> defined at CMakeFiles/zig2.dir/compiler_rt.c.obj
>>> defined at compiler_rt.lib(compiler_rt.lib.obj)
```

6c15d69660 Revert "ci: Build with ZIG2_NO_RTLIB on Windows machines." 
This reverts commit 7e66b6d0684fb1b3aa76381486e655e4d13bc0a5.

I don't think this is needed, I don't get any errors locally when I
bootstrap windows without this change.

335ed630a0 ci: Build with ZIG2_NO_RTLIB on Windows machines. 
Windows does not really have weak symbols. So when we bootstrap with `zig cc`
and link both Zig's compiler-rt and the CBE's `compiler_rt.c` we end up with
duplicate symbol errors at link time.

Sema: clean up cmpNumeric 
There is one minor language change here, which is that comparisons of
the form `comptime_inf < runtime_f32` have their results comptime-known.
This is consistent with comparisons against comptime NaN for instance,
which are always comptime known. A corresponding behavior test is added.

This fixes a bug with int comparison elision which my previous commit
somehow triggered. `Sema.compareIntsOnlyPossibleResult` is much cleaner
now!
