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.

For functions that return an argument unchanged, like strcat,
find_call_crossed_cheap_reg attempts to find an assignment between
a pseudo reg and the arg reg before the call, so that uses of the
pseudo after the call can instead use the return value. The exit
condition on the loop looking at previous insns was wrong. Uses of
the arg reg don't matter. What matters is the insn setting the arg
reg as any assignment involving the arg reg prior to that insn is
likely a completely unrelated use of the hard reg.
