Here, since the call to g is not type-dependent, we call mark_used on it to

Make function_code a 32-bit field
Adding SVE intrinsics on top of the existing AArch64 intrinsics blows
the 12-bit function_code in tree_function_decl. That bitfield has no
spare bits, but it comes at the end of the structure and is preceded
by a pointer, so on LP64 hosts there's currently a 32-bit hole at end.
This patch therefore makes function_code an independent field and
moves the bitfield to the 32-bit hole.
I wondered about instead making function_code 16 bits, so that the
patch leaves 28 spare bits instead of just 12. That seemed a bit
short-term though; I can't guarantee that we won't blow 16 bits once
the SVE2 functions are added...
If we run out of bits again, we can start chomping from the top
of the enum. E.g. 24 bits should surely be enough, but there's
no point paying the overhead of the masking until we need it.

rework Ada EH Machine_Occurrence deallocation
Introduce exception handler ABI #1 to ensure single release, no access
after release of reraised Machine_Occurrences, and no failure to
re-reraise a Machine_Occurrence.
Unlike Ada exceptions, foreign exceptions do not get a new
Machine_Occurrence upon reraise, but each handler would delete the
exception upon completion, normal or exceptional, save for the case of
a 'raise;' statement within the handler, that avoided the delete by
clearing the exception pointer that the cleanup would use to release
it. The cleared exception pointer might then be used by a subsequent
reraise within the same handler. Get_Current_Excep.all would also
expose the Machine_Occurrence to reuse by Reraise_Occurrence, even for
native exceptions.
Under ABI #1, Begin_Handler_v1 claims responsibility for releasing an
exception by saving its cleanup and setting it to Claimed_Cleanup.
End_Handler_v1 restores the cleanup and runs it, as long as it isn't
still Claimed_Cleanup (which indicates an enclosing handler has
already claimed responsibility for releasing it), and as long as the
same exception is not being propagated up (the next handler of the
propagating exception will then claim responsibility for releasing
it), so reraise no longer needs to clear the exception pointer, and it
can just propagate the exception, just like Reraise_Occurrence.
ABI #1 is fully interoperable with ABI #0, i.e., exception handlers
that call the #0 primitives can be linked together with ones that call
the #1 primitives, and they will not misbehave. When a #1 handler
claims responsibility for releasing an exception, even #0 reraises
dynamically nested within it will refrain from releasing it. However,
when a #0 handler is a handler of a foreign exception that would have
been responsible for releasing it with #1, a Reraise_Occurrence of
that foreign or other Machine_Occurrence-carrying exception may still
cause the exception to be released multiple times, and to be used
after it is first released, even if other handlers of the foreign
exception use #1.

PR c++/90538 - multiple expansions of capture packs
Previously, with init-capture the type of the closure field was a
DECLTYPE_TYPE of the initializer. But since each time we tsubst a lambda we
get a different lambda, that meant that if the initializer is a lambda, we'd
end up with different closure types in the field and initializer after
substitution (PR 87322). We dealt with this by remembering the lambda
instantiation within each pack expansion element, using
local_specialization_stack to separate the elements. But that broke this
testcase, because it lost lambda capture proxies that also use
local_specializations.
So, this patch removes the local_specializations changes from that patch and
fixes 87322 differently, by giving init-capture fields 'auto' type and doing
deduction later. There's a bit of a kludge to get the right number of
fields by pretending that 'auto...' uses the parameter packs from the
initializer, but it does the trick.
