Functions cmse_nonsecure_call_clear_caller_saved and
cmse_nonsecure_entry_clear_before_return both contain very similar code
to clear registers. What's worse, they differ slightly at times so if a
bug is found in one careful thoughts is needed to decide whether the
other function needs fixing too.
This commit addresses the situation by factoring the two pieces of code
into a new function. In doing so the code generated to clear VFP
registers in cmse_nonsecure_call now uses the same sequence as
cmse_nonsecure_entry functions. Tests expectation are thus updated
accordingly.

PR c/83056 reports an issue affecting trunk and gcc-7 in which
the C frontend's implementation of lookup_name_fuzzy uses undeclared
identifiers as suggestions when encountering subsequent undeclared
identifiers.
The fix is to filter out the names bound to error_mark_node
in lookup_name_fuzzy.
The C++ frontend is unaffected, as it already does this.
