rGc5471c2a5751: [ARM] Adjust isLegalT1AddressImmediate for non-legal types
rL362874: [ARM] Adjust isLegalT1AddressImmediate for non-legal types
Summary

Types such as float and i64's do not have legal loads in Thumb1, but will still be loaded with a LDR (or potentially multiple LDR's). As such we can treat the cost of addressing mode calculations as such and get some optimisation benefits.

Some of the tests are new, I'm just showing the differences for clarity.

This probably doesn't precisely match the generated code for all simple types, but it makes sense for at least i64/float/double. LGTM
