[ARM] Fix PR85203: cmse_nonsecure_caller returns wrong result · f4d43ef0

__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.

Fix -Wstringop-overflow regression · f1acdcd0

we shouldn't claim string overflows for character arrays at
end of structures; the code that tries to avoid these
accidentally passed the address of the accessed member to
array_at_struct_end_p(), but that one wants the component_ref
or array_ref itself.  Needs updating of one testcase that
incorrectly expected warning to occur in this situation.
