e681c0f7b3 O3: Support squashing all state after special instruction 
For SPARC ASIs are added to the ExtMachInst. If the ASI is changed simply
marking the instruction as Serializing isn't enough beacuse that only
stops rename. This provides a mechanism to squash all the instructions
and refetch them

719f9a6d4f O3: Make all instructions that write a misc. register not perform the write until commit. 
ARM instructions updating cumulative flags (ARM FP exceptions and saturation
flags) are not serialized.

Added aliases for ARM FP exceptions and saturation flags in FPSCR.  Removed
write accesses to the FP condition codes for most ARM VFP instructions: only
VCMP and VCMPE instructions update the FP condition codes.  Removed a potential
cause of seg. faults in the O3 model for NEON memory macro-ops (ARM).

0f039fe447 IGbE: return 0 on an invalid descriptor size instead of -1. 
Asserts where descSize() get called with assert if we end up returning
0.

b3de4855c3 Params: Add parameter types for IP addresses in various forms. 
New parameter forms are:
IP address in the format "a.b.c.d" where a-d are from decimal 0 to 255.
IP address with netmask which is an IP followed by "/n" where n is a netmask
length in bits from decimal 0 to 32 or by "/e.f.g.h" where e-h are from
decimal 0 to 255 and which is all 1 bits followed by all 0 bits when
represented in binary. These can also be specified as an integral IP and
netmask passed in separately.
IP address with port which is an IP followed by ":p" where p is a port index
from decimal 0 to 65535. These can also be specified as an integral IP and
port value passed in separately.

34a8e37c13 SE: Fix simulating more than 4GB of RAM in SE mode 
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.

92655b6399 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.

4876e0c92b 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".
