45cf2e3c34 arch: Minimize use of RegClassType constants and the RegId constructor. 
These are global values which prevent making register types ISA
specific.

4754e32219 arch-arm: Fixes an error related to HTM error code handling 
Arguments of the function bits(), called in restore method,
are the other way around.

This leads to wrong retry handling.

974a47dfb9 misc: Adopt the gem5 namespace 
Apply the gem5 namespace to the codebase.

Some anonymous namespaces could theoretically be removed,
but since this change's main goal was to keep conflicts
at a minimum, it was decided not to modify much the
general shape of the files.

A few missing comments of the form "// namespace X" that
occurred before the newly added "} // namespace gem5"
have been added for consistency.

std out should not be included in the gem5 namespace, so
they weren't.

ProtoMessage has not been included in the gem5 namespace,
since I'm not familiar with how proto works.

Regarding the SystemC files, although they belong to gem5,
they actually perform integration between gem5 and SystemC;
therefore, it deserved its own separate namespace.

Files that are automatically generated have been included
in the gem5 namespace.

The .isa files currently are limited to a single namespace.
This limitation should be later removed to make it easier
to accomodate a better API.

Regarding the files in util, gem5:: was prepended where
suitable. Notice that this patch was tested as much as
possible given that most of these were already not
previously compiling.

773368d68d arch-arm: Consolidate register related files into a directory. 
Create a directory called "regs" which holds files, primarily headers,
related to registers, with the exception of registers.hh. Hopefully
registers.hh will go away in the not too distant future, removing this
exception.
