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

The IC exposes a register definition.
Centralize a register definition in an IC that provides:
1) symbolic names for the register (like, edx == receiver)
2) defines ordering when passed on the stack
Code that implements or uses the IC should use this definition instead of "knowing" what the registers are. Or at least have the definition to validate it's assumptions.
As a side effect of avoiding runtime static initializers (enforced by tools/check-static-initializers.sh, neat), I gave ownership of the registers array to CodeStubInterfaceDescriptor. This prompted a cleanup of that struct.

When we fire a debug event, we create duplicate execution state objects,
