b45bbef206 tests,base: Fixed unittests for .fast 
unittests.fast, unittests.prof, and unittests.perf had failing tests due
to the stripping of asserts via compiler optimization. This patch alters
the unittests to skip these tests when TRACING_ON == 0.

93ccc23b4a base: Cleanup debug flags API 
The debug flags API has a couple of quirks that should be cleaned
up. Specifically:

 * Only CompoundFlag should expose a list of children.
 * The global enable flag is just called "active", this isn't very
   descriptive.
 * Only SimpleFlag exposed a status member. This should be in the base
   class to make the API symmetric.
 * Flag::Sync() is an implementation detail and needs to be protected.

e9075be4f9 base: Cleanup Debug::CompoundFlag 
Compound flags are currently constructed using a constructor with a
finite set of arguments that default to nullptr that refer to child
flags. C++11 introduces two cleaner ways to achieve the same thing,
variadic templates and initializer_list. Use an initializer list to
pass dependent flags.

e020184843 base: Make the Value stat's functor method accept lambdas. 
This class can already accept a proxy variable and a "functor" which is
a pointer to either a function or an instance of a class with the ()
operator overloaded.

This change adds a FunctorProxy partial specialization which accepts
anything that can be used to construct a std::function<Result()>. The
constructor argument is copied and stored in the proxy which makes it
possible to define a lambda inline without having to keep a copy of it
around for the proxy to point to.

Also, the ValueBase stat's functor method now has a second version which
accepts a const reference rather than just a reference to its argument.
We need both because when accepting a reference to a lambda it needs to
be a const reference, but when accepting a pointer to a functor object,
we don't want it to be const because that would force the () operator to
also be const.

82f881255d base: avoid recreating socket at each call to listen() 
A new socket was created each time listen() is called,
which is problematic when the bind or listen operation
on it are not successful (mostly because the associated port is
already in use). It can lead gem5 to open too many files and crash
for multicores configurations, a socket being created
for remote GDB for each core. The other way to deal with
this problem would be to close the socket in the case the
function return false. But I find the proposed solution
simpler.

tell was removed from elf.h in 1998.

9d1278d551 misc: Delete the critical path annotation code. 
This code was at least a little Alpha specific, and now that Alpha is
gone it can no longer be compiled. We could either fix it up to work
with other/all ISAs or delete it, and the consensus was to delete it. It
could potentially be revived in the future by retrieving it from version
control.

This type is templated on what arguments the callbacks in it accept, and
it inherits directly from std::list instead of containing one and
forwarding selected members.

This version is called CallbackQueue2, but once all CallbackQueue
instances have been replaced it will be renamed to CallbackQueue.

0f4ecba2a9 base,scons: -wno-deprecated-copy added for hdf5.cc with GCC 
As highlighted by Ciro here:
https://gem5-review.googlesource.com/c/public/gem5/+/31216, and
here: https://gem5.atlassian.net/browse/GEM5-365,  It appears that GCC
versions >= 9 requires `-wno-deprecated-copy` which was removed in
commit: https://gem5-review.googlesource.com/c/public/gem5/+/31216.
`-wno-deprecated-copy` appears to work for all versions of GCC. Clang
does not require `-wno-deprecated-copy` nor `-wno-deprecated` for
sucessfull compilation. Therefore branching has been introduced to the
SConscript to address this and simplify the solution.

b99c316840 base,arch: Fixed usage of bitfield::replaceBits 
`bitfield::replaceBits` has two parameters, `first` and `last`, which
relate to the position of the MSB and the LSB of the bits to be replaced
respectively. Therefore `first` >= `last`. In some areas of the
codebase, this assumption has been flipped with `first` <= `last`. This
caused at least one known error, recorded here:
https://gem5.atlassian.net/browse/GEM5-695. These inconsistencies have
therefore been rectified.

A note has been added to the `bitfield::replaceBits` Doxygen to make
the usage of this function clearer.

cc791d51a2 base,scons: Fixed stats/hdf5.cc CXXFlags to -Wno-deprecated 
`Wno-deprecated-copy` was added to disable a warning in hdf5.cc:
https://gem5-review.googlesource.com/c/public/gem5/+/26325.

This works with GCC but does not work with clang. Clang returns
`error: unknown warning option '-Wno-deprecated-copy'; did you mean
'-Wno-deprecated'? [-Werror,-Wunknown-warning-option]` when this flag
is enabled. This flag has therefore been changed to `Wno-deprecated`.
This works in both GCC and Clang.

This commit fixes a bug in 200f2408 where the SDWA support was selecting bits
backwards.  As part of this commit, to help resolve this problem in the
future, I have added asserts in the helper functions in bitfield.hh to ensure
that the number of bits aren't negative.
