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.

In GCN3, the v_add_u32, v_sub_u32, and v_subrev_u32 instructions write
the carry-out value to VCC. VEGA introduces explicit carry-out versions
of these instructions (v_add_co_u32, v_sub_co_u32, and v_subrev_co_u32),
and modifies the behavior of the baseline, non-carry-out versions to not
write to VCC. Previously both the carry-out and non-carry-out versions
shared a single implementation that wrote to VCC. This patch correctly
implements the non-carry-out versions to avoid the VCC write.
This patch also makes the following substitutions for GCN3 instructions
that no longer exist in VEGA (this renaming has no functional impact):
v_addc_u32 -> v_addc_co_u32
v_subb_u32 -> v_subb_co_u32
v_subbrev_u32 -> v_subbrev_co_u32

This commit removes functions that indexed into the
vectors that held the operands. Instead, for-each loops
are used, iterating through one of 6 vectors
(src, dst, srcScalar, srcVec, dstScalar, dstVec)
that all hold various (potentially overlapping)
combinations of the operands.

This change removes the GPUDynInstPtr argument from
getRegisterIndex(). The dynamic inst was only needed
to get access to its parent WF's state so it could
determine the number of scalar registers the wave was
allocated. However, we can simply pass the number of
scalar registers directly. This cuts down on shared
pointer usage.
