Daniel Sanders aa1b35590f [mips] Mark aggregate arguments passed in registers with the inreg attribute
Summary:
This allows us to easily identify them in the backend which in turn allows us
to handle them correctly for big-endian targets (where they must be shifted
into the upper bits of the register).

Depends on D5961
