Prior to this changeset the bootloader rom (instantiated as a
SimpleMemory) in ruby Arm systems was treated as an IO device and it
was fronted by a DMA controller. This changeset moves the bootloader
rom and adds it to the system as another memory with a dedicated
directory controller.

GCC 7 generates spurious fallthrough warnings in nested switch blocks
where the inner switch block return. There is already a GCC fix [1]
submitted for review but, until it is merged into GCC trunk, GEM5 will
not build with GCC 7 due to these fallthrough warnings. This patch
silences the spurious fallthrough warnings by appending a M5_UNREACHABLE
statement in the outer switch cases.
Note there is another GEM5 patch [2] to fix other fallthrough warnings.

If an instruction is invalid, some assertions may in the decoder may
fail the entire simulation. Instead, we want to raise an
IllegalInstFault instead of failing immediately in the decoder if the
invalid instruction is being speculatively executed.

gcc 7 onwards have additional heuristics to detect implicit
fallthroughs and it fails the build with warnings for ARM as a result.
There was one gcc bug[1] that I fixed but the rest are cases that gcc
cannot detect due to the point at which it does the fallthrough check.
Most of this patch adds __builtin_unreachable() hints in places that throw
this warning to indicate to gcc that the fallthrough will never
happen.
The remaining cases are actually possible fallthroughs due to
incorrect code running on the simulator; in which case an Unknown
instruction is returned.

Add bitfields which can gather/scatter base and limit fields within
"normal" segment descriptors, and in TSS descriptors which have the
same bitfields in the same positions for those two values.
This centralizes the code which manages those bitfields and makes it
less likely that a local implementation will be buggy.

These instructions originally read the TSC into t1 and then unpacked it
into eax and edx using a move, a right shift, and then another move.
We can combine the second shift and move. The shift will move the
upper 32 bits into the lower 32 bits, and clear the upper 32 bits to
zero. This has the same effect as moving the lower 32 bits post-shift
into another register, since the upper 32 bits will be cleared to zero
based on x86 partial register access semantics.

This is very similar to RDTSC, except that it requires all younger
instructions to retire before it completes, and it writes the TSC_AUX
MSR into ECX. I've added an mfence as an iniitial microop to ensure
that memory accesses complete before RDTSCP runs, and added an rdval
microop at the end to read the TSC_AUX value into ECX.

This makes it explicit which type of serialization you want, and also
makes it possible to make a macroop serialize before. The old
serializing directive was renamed .serialize_after in the microcode
assembler, and throughout the microcode implementation, and its
behavior is unchanged. More specifically, it still marks the last
microop within the macroop as IsSerializing and IsSerializeAfter.
The new .serialize_before directive does something similar and marks
the first microop as IsSerializing and IsSerializeBefore.

Only a small quantity of prefetches were issued, as the positive
feedback mechanism was not implemented. This commit adds a new
action po_observeHit, which notifies the RubyPrefetcher of
successful prefetches and resets the prefetch flag.
When a cache line was replaced by a prefetch, the wrong queue could
be stalled. This commit adds a new event PF_L1_Replacement, which
stalls the correct queue.
The behavior when receiving a prefetch or instruction fetch while
in PF_IS_I (prefetch caused GETs, but got invalidated before the
response was received) was undefined. This was changed to drop the
prefetch request or change the state to non-prefetch, respectively.
This behavior is analogous to IS_I (non-prefetch caused GETs, but
got invalidated before the response was received) and the data case,
respectively.
In my local branch a major (20+%) performance increase can be
observed in SPEC2006 gobmk and leslie3d when enabling the
prefetcher. Some other benchmarks like bwaves, GemsFDTD, sphinx and
wrf show smaller (~10%) performance increases. Unfortunately, the
performance in most other SPEC benchmarks is still poor, most likely
as the prefetcher does not detect strides fast/often enough. In
order to push the change timely (most benchmarks have runtimes in
the order of days on my machine even with the smallest parameters)
after checkout, I have only run gobmk with the base repository
+ this commit. The results match those of my local branch.

The fault status code generated by a Prefetch/Data Fault was containing
a wrong value when the fault was triggered in aarch32 but handled in
aarch64. This because the encoding differs between the two ISAs and the
encoder was just checking the starting ISA rather than the the ending
one. In this case the getFsr must be called after we know which is the
ending ISA, which happens only after ArmFault::invoke gets called. The
fsc update hence happens before writing into the Syndrome register.
