…eltypes (#34230)

In cases where we have multiple arrays with `OneTo` axes that do not share the same axis eltype, we should simply default to constructing a new array with `OneTo{Int}` axes.

There was a bug in initial value handling of `FlatteningRF` and the
following example failed:

    @test mapfoldl(
        x -> (x, x),
        ((a, b), (c, d)) -> (min(a, c), max(b, d)),
        Iterators.flatten((1:2, 3:4)),
    ) == (1, 4)

This is because `BottomRF(op.rf)` was called inside `FlatteningRF`
where `op.rf` is already a "non-bottom" reducing function; here it's a
`MappingRF`.  As `BottomRF(rf)` forwards anything on the second
argument on the first invocation as the first argument (accumulator)
of the next calls, we need to make sure that this value is processed
through `MappingRF` in the above example.  However, if we do
`BottomRF(op.rf)` where `op.rf` is a `MappingRF`, this `BottomRF`
bypasses any processing that has to happen in `op.rf`.

This fixes #34247 by changing the way gc preserve is lowered.
Instead of lowering it in a macro, lower it in the frontend.
This allows us to use an SSA value directly for the return token
of the gc begin expression. This bypasses the slot-renaming pass
of the compiler, thus preventing the compiler from trying to save
and restore the token. Of course, this kind of code would generally
not be legal (because it uses an SSA value outside of the regular
domination relation), but since this is a julia restriction, not
an LLVM restriction, we can simply exempt gc_begin tokens from this
particular validation. This works fine at the LLVM level also, because
it doesn't have this particular restriction. It also doesn't have
the same correctness problems as doing the same for non-token values,
as the tokens get lowered away by the try/catch lowering before reaching
the LLVM backend.

Fixes the same CI failure as #34336,
but hopefully should be immediately mergeable without objection about what
the interface is.

(cherry picked from commit 3ed4e94)

After much debugging, it turns out that OpenBlas is sometimes hanging
on exit due to bad assumptions in its thread management. The upstream
discussion is at OpenMathLib/OpenBLAS#2350, but this
should fix our frequent win32 CI failures in the meantime.

In both places we call it. Also tabs-to-spaces for the new code
to match the formatting of the rest of the code.
