`DEVELOPER_DIR` is the standard environment variable for overriding the
Xcode version, there is no need to invoke `xcode-select --switch`
manually to do this.

The variable is documented in both `man xcode-select` and `man xcrun`.

const-eval: always do mem-to-mem copies if there might be padding involved

This is the final piece of the puzzle for rust-lang#148470: when copying data of a type that has padding, always do a mem-to-mem copy, so that we always preserve the source padding exactly. That prevents rustc implementation choices from leaking into user-visible behavior.

This is technically a breaking change: the example at the top of rust-lang#148470 no longer compiles with this. However, it seems very unlikely that anyone would have depended on this. My main concern is not backwards compatibility, it is performance.

Fixes rust-lang#148470

> Actually that seems to be entirely fine, it even helps with some benchmarks! I guess the mem-to-mem codepath is actually faster than the scalar pair codepath for the copy itself. It can slow things down later since now we have to do everything bytewise, but that doesn't show up in our benchmarks and might not be very relevant after all (in particular, it only affects types with padding, so the rather common wide pointers still always use the efficient scalar representation).
>
> So that would be my proposal to for resolving this issue then: to make const-eval behavior consistent, we always copy the padding from the source to the target. IOW, potentially pre-existing provenance in the target always gets overwritten (that part is already in rust-lang#148259), and potentially existing provenance in padding in the source always gets carried over (that's rust-lang#148967). If there's provenance elsewhere in the source our existing handling is fine:
> - If it's in an integer, that's UB during const-eval so we can do whatever.
> - If it's in a pointer, the the fragments must combine back together to a pointer or else we have UB.
> - If it's in a union we just carry it over unchanged.
>
> @traviscross we should check that this special const-eval-only UB is properly reflected in the reference. Currently we have [this](https://doc.rust-lang.org/nightly/reference/behavior-considered-undefined.html#r-undefined.const-transmute-ptr2int) but that only talks about int2ptr, not about invalid pointer fragments at pointer type. I also wonder if this shouldn't rather be part of ["invalid values"](https://doc.rust-lang.org/nightly/reference/behavior-considered-undefined.html#r-undefined.validity) to make it clear that this applies recursively inside fields as well.

> Worth noting that this does not resolve the concerns @theemathas had about `-Zextra-const-ub-checks` sometimes causing *more* code to compile. Specifically, with that flag, the behavior changes to "potentially existing provenance in padding in the source never gets carried over". However, it's a nightly-only flag (used by Miri) so while the behavior is odd, I don't think this is a problem.

Use `DEVELOPER_DIR` instead of a custom `xcode-select` script

`DEVELOPER_DIR` is the standard environment variable for overriding the Xcode version, there is no need to invoke `xcode-select --switch` manually to do this.

The variable is documented in both `man xcode-select` and `man xcrun`.

Using this makes reproducing things locally a little easier (you can just copy the env var).

Fix some autodiff tests require Clto=fat

It seems that some tests in tests/run-make/autodiff/type-trees/ require -Clto=fat at least on macos

There are several types of errors in tests/run-make/autodiff now. I fixed the easiest one to reduce the noise. I'll look into another errors after this PR.

I confirmed tests have passed.
