There's a mechanism to get type (and decl - I suppose CTF also
contains debug info
for function declarations not only its type?) info as part of early
debug generation.

This addresses PR 91860 which has four testcases triggering internal errors.
The problem here is that in combine when handling debug insns, we are trying
to substitute
(sign_extend:DI (const_int 8160 [0x1fe0]))
as the value for
(reg:DI 78 [ _9 ])
in the debug insn
(debug_insn 29 28 30 2

PR79262 has been fixed for almost all AArch64 cpus, however the example is still
vectorized in a few cases, resulting in lower performance. Increase the cost of
vector-to-scalar moves so it is more similar to the other vector costs. As a
result
-mcpu=cortex-a53 no longer vectorizes the
