71c4b000b3 Don't special-case power-of-2 replacement policy for BTB
PLRU wasn't implemented correctly for the BTB, since it wasn't
increasing the priority on replacement, only on usage.  Regardless,
this should be a second-order effect, so using FIFO always is fine.

7e794212d9 Cleanup emulator.cc, use getopt, add help text (#487)
This changes the emulator to conform to POSIX-style options (e.g.,
short/'-' and long/'--') while preserving legacy option parsing (i.e.,
'+'). Options are read from the user until the first
non-option (either POSIX or legacy) is encountered. This and
everything following is assumed to be the binary and any arguments the
user wants to run on the emulator. All non-options are passed directly
to the DTM. This allows for the same option to be passed, safely, to
both the emulator and the binary, e.g., "+verbose".

This introduces a dependency on <getopt.h>.

Closes #484.

09afbbafdb ahb: weaken RegisterRouter assertion
As written I think it could potentially fail, but what I actually care
about is something weaker that should be true. Assert: nothing lost.
