485697bf42 Better way of conditioning the sanitizer builds 
Previously the build would take the presence of the LLVM_CONFIG envvar to
mean that the sanitizers should be built, but this is a common envvar that
could be set for reasons unrelated to the rustc sanitizers.

This commit adds a new envvar RUSTC_BUILD_SANITIZERS and uses it instead.

Rollup merge of #64141 - nnethercote:minimize-LocalInternedString, r=petrochenkov 
Minimize uses of `LocalInternedString`

`LocalInternedString` is described as "An alternative to `Symbol` and `InternedString`, useful when the chars within the symbol need to be accessed. It is best used for temporary values."

This PR makes the code match that comment, by removing all non-local uses of `LocalInternedString`. This allows the removal of a number of operations on `LocalInternedString` and a couple of uses of `unsafe`.

Rollup merge of #64123 - danielhenrymantilla:add_comment_about_uninit_integers, r=Centril 
Added warning around code with reference to uninit bytes

Officially, uninitialized integers, and therefore, Rust references to them are _invalid_ (note that this may evolve into official defined behavior (_c.f._, https://github.com/rust-lang/unsafe-code-guidelines/issues/71)).

However, `::std` uses references to uninitialized integers when working with the `Read::initializer` feature (#42788), since it relies on this unstably having defined behavior with the current implementation of the compiler (IIUC).

Hence the comment to disincentivize people from using this pattern outside the standard library.

Harden `param_attrs` test wrt. usage of a proc macro `#[attr]`

The `param-attrs-builtin-attrs.rs` test file uses the `#[test]` attribute which should cover this but `#[test]` isn't a proc macro attribute so we add another test to be on the safe side. This intends to address https://github.com/rust-lang/rust/pull/64010#issuecomment-526564316.

Rollup merge of #64005 - ecstatic-morse:is-indirect, r=oli-obk 
Add a `Place::is_indirect` method to determine whether a `Place` contains a `Deref` projection

Working on #63860 requires tracking some property about each local. This requires differentiating `Place`s like `x` and `x.field[index]` from ones like `*x` and `*x.field`, since the first two will always access the same region of memory as `x` while the latter two may access any region of memory. This functionality is duplicated in various places across the compiler. This PR adds a helper method to `Place` which determines whether that `Place` has a `Deref` projection at any point and changes some existing code to use the new method.

I've not converted `qualify_consts.rs` to use the new method, since it's not a trivial conversion and it will get replaced anyway by #63860. There may be other potential uses besides the two I change in this PR.

53fe76479a Assume non-git LLVM is fresh if the stamp file exists 
Rustbuild usually writes the LLVM submodule commit in a stamp file, so
we can avoid rebuilding it unnecessarily. However, for builds from a
source tarball (non-git), we were assuming a rebuild is always needed.
This can cause a lot of extra work if any environment like `CFLAGS`
changed between steps like build and install, which are often separate
in distro builds.

Now we also write an empty stamp file if the git commit is unknown, and
its presence is trusted to indicate that no rebuild is needed. An info
message reports that this is happening, along with the stamp file path
that can be deleted to force a rebuild anyway.
