When lowering a decl value we verify whether its owner decl index
equals to the decl index of the decl being lowered. When this is not
the case, we are lowering an alias. So instead, we will now lower
the owner decl instead and call its symbol to ensure its type
is being correctly generated.
When compiling Zig code using the Wasm backend, we would previously
incorrectly resolve exported symbols as it would not correctly remove
existing symbols if they were to be overwritten. This meant that
undefined symbols could cause collisions although they should be
resolved by the exported symbol.
Calling into coercion logic here is a little opaque, and more to the
point wholly unnecessary. Instead, the (very short) logic is now
implemented directly in Sema.
Resolves: #16033
Previously, this logic was split between Sema.coerceValueInMemory and
InternPool.getCoerced. This led to issues when trying to coerce e.g. an
optional containing an aggregate, because we'd call through to
InternPool's version which only recurses on itself so could not coerce
aggregates. Unifying them is fairly simple, and also simplified a bit of
logic in Sema.
Also fixes a key lifetime bug in aggregate coercion.
This allows tuples whose fields are in-memory coercible to themselves be
coerced in memory. No InMemoryCoercionResult field has been added, so in
future one could be added to improve error messages.
The existing logic for peer type resolution was quite convoluted and
buggy. This rewrite makes it much more resilient, readable, and
extensible. The algorithm works by first iterating over the types to
select a "strategy", then applying that strategy, possibly applying peer
resolution recursively.
Several new tests have been added to cover cases which the old logic did
not correctly handle.

Failing to forward free calls to the underlying allocator makes
`ValidationAllocator` unusable for testing allocators while checking for
leaks. This change allows allocators that wrap `std.testing.allocator`
to be tested with `std.heap.testAllocator()` in test decls without
reporting erroneous leaks.

To do this, I expanded SwitchProngSrc a bit. Several of the tags there
aren't actually used by any current errors, but they're there for
consistency and if we ever need them.
Also delete a now-redundant test and fix another.
