  [ADT] Add `SmallVector::assign` overload for `ArrayRef` (#164680)

We already have a matching constructor from ArrayRef, so add support for
assigning from ArrayRef as well.

This testcase shows that adding a ubsan check and then removing it
during the LowerAllowCheck pass does not entirely undo the effects of
adding the check.

  [mlir][acc] Add mapping operation for firstprivate without counter (#164677)

The OpenACC data clause operation `acc.copyin` used for mapping
variables to device memory includes bookkeeping required by the OpenACC
spec for updating present counters. However, for firstprivate variables,
no counters should be updated since this clause creates a private copy
on the device initialized with the original value from the host (as
described in OpenACC 3.4 section 2.5.14: "the copy will be initialized
with the value of that item on the local thread").

This PR introduces the `acc.firstprivate_map` operation to capture these
mapping semantics without counter updates. A test is included
demonstrating how this operation can be used to initialize a
materialized private variable (represented by `memref.alloca` inside an
`acc.parallel` region).

Test update was missed in bfc322dd724735 due a codegen test running
loop-vectorize directly. The loop does not get vectorized any longer.

  [clang] Refactor `ASTUnit::LoadFromASTFile()` (#164265)

This PR refactors `ASTUnit::LoadFromASTFile()` to be easier to follow.
Conceptually, it tries to read an AST file, adopt the serialized
options, and set up `Sema` and `ASTContext` to deserialize the AST file
contents on-demand.

The implementation of this used to be spread across an
`ASTReaderListener` and the function in question. Figuring out what
listener method gets called when and how it's supposed to interact with
the rest of the functionality was very unclear. The `FileManager`'s VFS
was being swapped-out during deserialization, the options were being
adopted by `Preprocessor` and others just-in-time to pass `ASTReader`'s
validation checks, and the target was being initialized somewhere in
between all of this. This lead to a very muddy semantics.

This PR splits `ASTUnit::LoadFromASTFile()` into three distinct steps:
1. Read out the options from the AST file.
2. Initialize objects from the VFS to the `ASTContext`.
3. Load the AST file and hook it up with the compiler objects.

This should be much easier to understand, and I've done my best to
clearly document the remaining gotchas.

(This was originally motivated by the desire to remove
`FileManager::setVirtualFileSystem()` and make it impossible to swap out
VFSs from underneath `FileManager` mid-compile.)
