Fix passing MACOSX_DEPLOYMENT_TARGET to the linker
I messed up in https://github.com/rust-lang/rust/pull/103929 when merging the two base files together and as a result, started ignoring `MACOSX_DEPLOYMENT_TARGET` at the linker level. This ended up being the cause of nighty builds not running on older macOS versions.
My original hope with the previous PR was that CI would have caught something like that but there were only tests checking the compiler target definitions in codegen tests. Because of how badly this sucks to break, I put together a new test via `run-make` that actually confirms the deployment target set makes it to the linker instead of just LLVM.
Closes https://github.com/rust-lang/rust/issues/104570 (for real this time)
This avoids creation of a terminating scope in
chains that contain both && and ||, because
also there we know that a terminating scope is
not neccessary: all the chain members are already
in such terminating scopes.
Also add a mixed && / || test.
Previously a short circuiting && chain would drop the
first element after all the other elements, and otherwise
follow evaluation order, so code like:
f(1).g() && f(2).g() && f(3).g() && f(4).g()
would drop the temporaries in the order 2,3,4,1. This made
&& and || non-associative regarding drop order, so
adding ()'s to the expression would change drop order:
f(1).g() && (f(2).g() && f(3).g()) && f(4).g()
for example would drop in the order 3,2,4,1.
As, except for the bool result, there is no data returned
by the sub-expressions of the short circuiting binops,
we can safely discard of any temporaries created by the
sub-expr. Previously, code was already putting the rhs's
into terminating scopes, but missed it for the lhs's.
This commit addresses this "twist". In the expression,
we now also put the lhs into a terminating scope.
The drop order for the above expressions is 1,2,3,4
now.

Restore `use` suggestion for `dyn` method call requiring `Sized`
Add the suggestion back that I accidentally removed in 88f2140d87 because I didn't understand that suggestion was actually useful...
Fixes#105159
Remove useless borrows and derefs
They are nothing more than noise.
<sub>These are not all of them, but my clippy started crashing (stack overflow), so rip :(</sub>
Previously, the `recover_local_after_let` function was called from the
body of the `recover_stmt_local` function. Unifying these two functions
make it more simple and more readable.
Don't elide type information when printing E0308 with `-Zverbose`
When we pass `-Zverbose`, we kinda expect for all `_` to be replaced with more descriptive information, for example --
```
= note: expected fn pointer `fn(_, u32)`
found fn item `fn(_, i32) {foo}`
```
Where `_` is the "identical" part of the fn signatures, now gets rendered as:
```
= note: expected fn pointer `fn(i32, u32)`
found fn item `fn(i32, i32) {foo}`
```
