Description:
X87: The IC exposes a register definition.
port r22011
original commit message:
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
