[ARM] Fix PR85203: cmse_nonsecure_caller returns wrong result
__builtin_cmse_nonsecure_caller implementation returns true in almost
all cases due to 2 separate bugs:
* gen_addsi is used instead of gen_andsi to retrieve the lsb
* the lsb boolean value is not negated but the specification says
the intrinsic should return true for a nonsecure caller and a
nonsecure caller is characterized with LR's lsb being 0
This was not caught due to (1) lack of runtime test and (2) the existing
RTL scan not taking into account that '.' matches newline in Tcl regular
expressions.
This commit fixes the implementation issues and improves testing of
cmse_nonsecure_caller by (1) adding a runtime test for the secure caller
case and (2) looking for an SET insn of an AND expression in the right
function. This leaves the nonsecure caller case only partly tested
since the exact value being AND and the negation are not covered by the
scan and the existing test infrastructure does not allow 2 separate
compilation and link to be performed. It is enough though to catch the
current incorrect behavior.
The commit also reorganize the scan directives in cmse-1.c to more
easily identify what function they are intended to test in the file.

[PR c++/84943] mark function as used when taking its address
fn[0]() ICEd because we would fold the INDIRECT_REF used for the
array indexing while building the address for the call, after not
finding the decl hiding there at first. But the decl would be exposed
by the folding, and then lower layers would complain we had the decl,
after all, but it wasn't one of the artificial or special functions
that could be called without being marked as used.
This patch arranges for a FUNCTION_DECL to be marked as used when
taking its address, just like we already did when taking the address
of a static function to call it as a member function (i.e. using the
obj.fn() notation). However, we shouldn't mark functions as used when
just performing overload resolution, lest we might instantiate
templates we shouldn't, as in g++.dg/overload/template1.C, so we
adjust mark_used to return early when testing conversions.
