Due to certain changes made via changeset 8229, the compilation was failing
in certain cases. The compiler pointed to base/stats/mysql.hh for not naming
a certain types like uint64_t. To rectify this, base/types.hh is being
included in base/stats/mysql.hh.
This change makes the decoder figure out if an instruction that only supports
memory is using a register encoding and decodes directly to "Unknown" which will
behave appropriately. This prevents other parts of the instruction creation
process from seeing the mismatch and asserting.
This is similar to guards on mercurial queues and they're used for selecting
which files are compiled into some given object. We already do something
similar, but it's mostly hard coded for the m5 binary and the m5 library
and I'd like to make it more flexible to better support the unittests
At the same time, rename the trace flags to debug flags since they
have broader usage than simply tracing. This means that
--trace-flags is now --debug-flags and --trace-help is now --debug-help
I didn't realize that the perl version existed when I started this,
this version has a lot more features than the previous one since it will
sort and separate python, system, and m5 headers in separate groups, it
will remove duplicates, it will also convert c headers to stl headers
This is basically like the range_map stuff in src/base (range already
exists in Python). This code is like a set of ranges. I'm using it
to keep track of changed lines in source code, but it could be use to
keep track of memory ranges and holes in memory regions. It could
also be used in memory allocation type stuff. (Though it's not at all
optimized.)

This patch moves the assignment of testsys.switch_cpus, testsys.switch_cpus_1,
switch_cpu_list, and switch_cpu_list1 outside of the for loop so they are
assigned only once, after switch_cpus and switch_cpus_1 are constructed.
This change fixes a small bug in the arm copyRegs() code where some registers
wouldn't be copied if the processor was in a mode other than MODE_USER.
Additionally, this change simplifies the way the O3 switchCpu code works by
utilizing TheISA::copyRegs() to copy the required context information
rather than the adhoc copying that goes on in the CPU model. The current code
makes assumptions about the visibility of int and float registers that aren't
true for all architectures in FS mode.
