This change removes some dead code in PhysicalMemory, uses a 64 bit type
for the page pointer in System (instead of 32 bit) and cleans up some style.

O3: Fix fp destination register flattening, and index offset adjusting.
...
This change makes O3 flatten floating point destination registers, and also
fixes misc register flattening so that it's correctly repositioned relative to
the resized regions for integer and floating point indices.
It also fixes some overly long lines.

Config: Change misleading "cycle" message to say "tick".
...
Most of the messages in the config scripts that report a time value already
print "@ tick" followed by the current tick value, but a few were printing
"@ cycle". Since this is a distinction that's frequently confusing to new
users, this changes those message to the more accurate and consistent "@ tick".

ARM: Don't return the result of a table walk the same cycle it's completed.
...
The L1 cache may have been accessed to provide this data, which confuses
it, if it ends up being accesses twice in one cycle. Instead wait 1 tick
which will force the timing simple CPU to forward to its next clock cycle
when the translation completes.
Also prevent multiple outstanding table walks from occuring at once.
