[ARM] Allow any register for DImode values in Thumb2
Ramana commented in the submission email:
I noticed that for T32 we don't allow any old register for DImode
values. The restriction of an even register is true only for ARM state
because the ISA doesn't allow any old register in this place. In a few
large .i files that I had knocking about, noticed a nice drop in stack
usage and a generally improved register allocation strategy.

compiler: Don't convert function type for an interface method.
For an interface method the function type is the type without
the receiver, which is wrong since we are passing a receiver.
The interface method will always have the correct type in this
case, so no type conversion is necessary.
Also don't do the type conversion when calling a named
function, since in that case the type is also always correct.
The type can be wrong, and the conversion required, when the
function type refers to itself recursively.
