In this PR we have a situation where we aren't really detecting
weak references vs weak definitions. If one has a weak definition that
binds locally there's no reason not to put out PC relative
relocations.
However if you have a genuine weak reference that is known not to bind
locally it makes very little sense to put out an entry into the
literal pool which doesn't always work with DSOs and shared objects.

condition on the loop looking at previous insns was wrong. Uses of

This patch sets the branch cost to the same most optimal setting for all Cortex
cores, reducing codesize and improving performance due to using more CSEL
instructions. Set the autoprefetcher model in Cortex-A72 to weak like the
others. Enable AES fusion in Cortex-A35. As a result generated code is now
more similar as well as more optimal across Cortex cores.

This patch fixes a bug in the bswap pass. In big-endian BIT_FIELD_REF uses
big-endian bit numbering so we need to adjust the bit position.
The existing version could potentially generate incorrect code however GCC

symbolic number never matches in big-endian.
