Fix another aspect of PR7047, macro expansions. Previously, this was hacked
...
around by exempting enums from the check, but this doesn't handle a lot of
cases. A better approach is to directly check if the operator comes from
a macro expansion.
I've removed a reference to the rdar that originally led to the enum
suppression when removing it's overly contrived test case. Let me know if that
number or a more reasilistic test case involving enums is still needed.

Convert the last use of getPhysicalRegisterRegClass and remove it.

AggressiveAntiDepBreaker should not be using getPhysicalRegisterRegClass. An
instruction might be using a register that can only be replaced with one from
a subclass of getPhysicalRegisterRegClass.
With this patch we use getMinimalPhysRegClass. This is correct, but
conservative. We should check the uses of the register and select the
largest register class that can be used in all of them.

Don't use getPhysicalRegisterRegClass in PBQP. The existing checks that the

it should be possible to coalesce two virtual registers the class of one
is a subclass of the other.
