- Update register allocation hint after coalescing. This is done by the target since the hint is target dependent. This is important for ARM register pair hints.

This fixes a bug introduced in 72661, which can
...
move loads back past a check that the load address
is valid, see new testcase. The test that went
in with 72661 has exactly this case, except that
the conditional it's moving past is checking
something else; I've settled for changing that
test to reference a global, not a pointer. It
may be possible to scan all the tests you pass and
make sure none of them are checking any component
of the address, but it's not trivial and I'm not
trying to do that here.
