Fix emulator argument processing for unknown DTM arguments ( #498 )
...
Revision 7e79421
(issue #484 ) makes emulator.cc rejecting any unrecognized
+arg "legacy" arguments, however, this breaks riscv-torture emulator tests
as it needs to pass +signature to the DTM.
I think it is actually impossible to check for unknown argument here
unless we hardcode a list of all arguments recognized by fesrv. Fix this
issue by passing all arguments starting with the first unknown argument
to DTM.
Updates #484 .

Configs: use a uniform syntax without Match exceptions ( #507 )
...
* Configs: use a uniform syntax without Match exceptions
The old style of specifying Configs used total functions. The only way to
indicate that a key was not matched was to throw an exception. Not only was
this a performance concern, but it also caused confusing error messages
whenever you had a match failure from a lookup within a lookup. The
exception could get handled by an outer-lookup that then reported the wrong
key as missing.

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.
