This patch fixes the ICE in the PR by bailing out of find_bswap_or_nop
on poly_int sizes.
I don't think it intends to handle them and from my reading of the code
it's the most appropriate place to reject them
here rather than in the callers.
Bootstrapped and tested on aarch64-none-linux-gnu.

This makes us always use a single-bit boolean type component type
for integer mode mask VECTOR_BOOLEAN_TYPE_P to match the RTL and target
representation. This aovids the need for magic translation and
the inconsistencies from the translation requirement now that
we expose temporaries of those types on the GIMPLE level.

Duplicate the cmpstrn pattern for cmpmem. The only difference is that
the length argument of cmpmem is guaranteed to be less than or equal to
lengths of 2 memory areas. Since "repz cmpsb" can be much slower than
memcmp function implemented with vector instruction, see

the default duplicate and insert methods of sumaries produce empty

A wrong decl for findloc caused segfaults at runtime on
Darwin for ARM; however, this is only a symptom of a larger
disease: The declarations for our library functions are often
inconsistent. This patch solves that problem for the functions
specifically for the functions for which we do not pass optional
arguments, i.e. findloc and (min|max)loc.
It works by saving the symbols of the specific functions in
gfc_intrinsic_namespace and by generating the formal argument
lists from the actual argument lists. Because symbols are
re-used, so are the backend decls.
