MIPS: Cleanup CallInterfaceDescriptor.

Port r22014 (234866c)

Original commit message:
Make CallInterfaceDescriptor work like CodeStubInterfaceDescriptor, owning it's
register and representation arrays. This also eliminates a host of TSAN warnings
for static arrays.

This CL depends on https://codereview.chromium.org/352583002 landing first
(a conceptual dependency at least).
