Update the minimum external LLVM to 13
With this change, we'll have stable support for LLVM 13 through 15 (pending release).
For reference, the previous increase to LLVM 12 was #90175.

The updated encoding should be able to handle niche layouts where
more than one variant has fields.
RustWrapper: update for TypedPointerType in LLVM2022-08-04T15:31:57+00:00Augie Fackleraugie@google.com2022-08-04T15:31:01+00:00urn:sha1:cdbe956ec386b3ffa6c8d03c2bea178394d09095

Add elementtype attributes for llvm.arm.ldrex/strex intrinsics2022-07-27T14:19:07+00:00Nikita Popovnpopov@redhat.com2022-07-19T13:03:39+00:00urn:sha1:f653d3ab30d4cab73af560f39b448ece2a49ff6c
These intrinsics (and a few more, but there are the only ones
exposed by stdarch) require an elementtype attribute in LLVM 15.

Remove dead code from cg_llvm
Found while working on https://github.com/rust-lang/rust/pull/97485
codegen: use new {re,de,}allocator annotations in llvm2022-07-26T13:43:28+00:00Augie Fackleraugie@google.com2022-03-21T19:30:54+00:00urn:sha1:130a1df71ea73ab9d66d3cb8fc9cdb43155d514b
This obviates the patch that teaches LLVM internals about
_rust_{re,de}alloc functions by putting annotations directly in the IR
for the optimizer.
The sole test change is required to anchor FileCheck to the body of the
`box_uninitialized` method, so it doesn't see the `allocalign` on
`__rust_alloc` and get mad about the string `alloca` showing up. Since I
was there anyway, I added some checks on the attributes to prove the
right attributes got set.
While we're here, we also emit allocator attributes on
__rust_alloc_zeroed. This should allow LLVM to perform more
optimizations for zeroed blocks, and probably fixes #90032. [This
comment](https://github.com/rust-lang/rust/issues/24194#issuecomment-308791157)
mentions "weird UB-like behaviour with bitvec iterators in
rustc_data_structures" so we may need to back this change out if things
go wrong.
The new test cases require LLVM 15, so we copy them into LLVM
14-supporting versions, which we can delete when we drop LLVM 14.
