There is no benefit for this split except perhaps for making the indexes
bit smaller and possibly better encodable by ulebs. This however does not
pay back and makes things unnecesarily complex.
We may want to re-add multiple tables if we start streaming something else than
trees into the global stream, but that would not work with current
infrastructure anyway.
The patch drops different streams and I checked that it results in reduction of
global stream and apparently very small increase in function streams but it may
be just because I updated tree in between the tests. This will be fixed by
incremental patch.

The patch also removes some of ugly macro generators of accessors functions and
makes it easier to further optimize the way we stream references to trees which
I plan to do incrementally.
I also made the API for streaming referneces symmetric. I.e. you
stream out by
lto_output_var_decl_ref
and stream in by
lto_input_var_decl_ref
instead streaming out by
lto_output_var_decl_index
and streaming in by

coroutines: Avoid functions with unlowered coroutine trees [PR95087].
Diagnosing bad uses of 'return' in coroutines is somewhat
tricky, since the user can use the keyword before we know
that the function is a coroutine (where such returns are not
permitted). At present, we are just doing a check for any
use of 'return' and erroring on that. However, we can't then
pass the function body on, since it will contain unlowered
coroutine trees.
This avoids the issue by dropping the entire function body

> Can't hurt, and debugging the assert tripping is likely a hell of a lot easier

Testing passed, so I've committed it with those asserts (and thankfully I've
added them!) but it apparently broke Linux kernel build on arm.
The problem is that if the STRING_CST is very short, while the full object
has BLKmode, the short string could very well have
QImode/HImode/SImode/DImode and in that case it wouldn't take the path that
copies the string and then clears the remaining space, but different paths
in which it will ICE because of those asserts and without those it would
just emit wrong-code.
The following patch fixes it by enforcing BLKmode for the string MEM, even
if it is short, so that we copy it and memset the rest.

Simplify tree streaming.
this patch cleans up tree streaming. The code is prepared to stream nested
trees, but we only handle flat trees. As a result we have quite heavy function
to stream in/out tree reference which is used many times and shows up in
profile.
This patch adds stream_write_tree_ref/stream_read_tree_ref which is used to
stream references to trees that are required to exist in the cache or be
indexable.
The actual implementation is just a first cut. I would like to make it more
compact. We used to stream 2 byte tag (as UHWI) + UHWI representing the index.
Now we stream one UHWI that represent type of reference + index for references
to cache, but still two integers for references to global stream. This is
becaue the abstraction is not very helpful here and I want to clean this up
incrementally.
I would also like to get rid of the ref_p parameters which seems unnecessary for
flat streams.
This reduces around 7% of global stream, 3% when compressed.
More reduction will happen once the format is sanitized a bit.

c++: lambdas inside constraints [PR92652]
When parsing a constraint-expression, a requires-clause or a
requires-expression, we temporarily increment processing_template_decl
so that we always obtain template trees which we could later reduce via
substitution even when not inside a template.
But incrementing processing_template_decl when we're already inside a
template has the unintended side effect of shifting up the template
parameter levels of a lambda defined inside one of these constructs,
which leads to confusion later during substitution into the lambda.
This patch fixes this issue by incrementing processing_template_decl
during parsing of these constructs only if it is 0.
Passes 'make check-c++', and also tested by building cmcstl2, does this
look OK to commit after a full bootstrap/regtest?
