Enable walking into `TypeOffsetSizePair`s from an existential into an
archetype. And set the access kind on `open_existential_addr`
instructions which are the sources of rewritten `copy_addr`s to mutable.

Kicking the interface type request of the base decl here is wrong
if the decl is e.g a `self` capture in a closure, since we'll be in
the middle of type-checking the closure. I'm planning on properly
fixing this by folding the lookup into the constraint system, but for
now let's at least avoid kicking the request if we don't have an enum
case or enum var. That at least prevents it from affecting cases where
e.g you're pattern matching against a property in a class.
We could potentially tighten up the checking here even further, but
that could potentially impact source compatibility for ambiguous
cases. I'd like to keep this patch low risk, and then deal with any
fallout as part of the pattern type-checking work.

Fixes a crash when existing logic cannot properly determine whether
argument is resolved or not.
Instead of ad-hoc code that checks `ResolvedOverloads` directly, let's
use a method that would reach of a callee locator to determine whether
argument is a reference to a generic function or not.

`typeCheck{Expression, Target}` has a pre-check phase which would
replace some invalid AST nodes (i.e. name references that are not
available in the given declaration context) with `ErrorExpr`s and
emit a diagnostic. Such diagnostics were then dropped by `abort()`
call to a diagnostic transaction. This results in invalid code being
accepted by Sema and forwarded to SILGen.

A big test was disabled due to one module failing to verify with
sil-opt. This PR reenables the test for all other modules to catch
errors while this particular problem is being looked into.

The test was using the default value for SWIFT_BUILD_ROOT, which tried
to write into `.build_script_log`. Use an environment variable so the
tests use their own directory and write files that do not append to the
actual `.build_script_log`.
Follow up to #80102
Selectively revert 36683a804c to resolve
a source compatibility regression. See inline comment for use case. We
are going to consider acknowledging this use case in the rules in a
future release.
The test run time jumped from ~200s to ~600s on Linux.
Unfortunately I could not reproduce this locally.
But what I saw is that ARCSequenceOpts is taking 75% of the compile time: rdar://144863155
Let's increase the timeout a bit until we can get rid of ARCSequenceOpts.

While materializing one metadata pack, another pack may need to be
materialized. When that happens, the inner pack's dynamically sized
allocation must be deallocated within the same dominance scope.
The CFG within which the inner dynamically sized pack is allocated isn't
visible from SIL; that explains why the existing infrastructure around
`de`/`alloc_pack_metadata` instructions fails to produce a deallocation
at the appropriate point.
In the fullness of time, this emitted code should be optimized such that
the inner loop is hoisted out of its current outer loop.

This was quite brittle and has now been superseded
by swift-xcodegen. Remove the CMake/build-script
logic for it, leaving the option behind to inform
users to switch to using xcodegen instead.
It looks like in this configuration we need to convince `build-script`
we have `ninja` sources in the worktree.
