makeExtMI no longer exists. It was absorbed into the predecoder and
uses the thread context to get whatever state it needs. This state
is the committed state, I believe, so it would miss younger
speculative execution.

FS#192 - Fix makeExtMI to be more flexible with ISAs
User who did this: - Ali Saidi (saidi)
Attached to Project - M5 Bugs
Summary - Fix makeExtMI to be more flexible with ISAs
Task Type - Bug
Category - CPU
Status - New
Assigned To - Kevin Lim
Operating System - All
Severity - Medium
Priority - Normal
Reported Version - 1.1
Due in Version - Due Date - Undecided
Percent Complete - 0%
Details - Currently makeExtMI is defined differently per-ISA, forcing
an if-def on the ISA in the CPU's fetch code. It'd be nice to fix
this.
Some possibilities:
Make ThreadContext for fetch stage. This might be a little overkill
for one function.
Have makeExtMI take in a fetch object, or fetch data structure that
has the necessary information for making the extended MI. This might
force other models such as SimpleCPU to create a fetch object.
