Use the PyBind11 wrapping infrastructure instead of SWIG to generate
wrappers for functionality that needs to be exported to Python. This
has several benefits:
* PyBind11 can be redistributed with gem5, which means that we have
full control of the version used. This avoid a large number of
hard-to-debug SWIG issues we have seen in the past.
* PyBind11 doesn't rely on a custom C++ parser, instead it relies on
wrappers being explicitly declared in C++. The leads to slightly
more boiler-plate code in manually created wrappers, but doesn't
doesn't increase the overall code size. A big benefit is that this
avoids strange compilation errors when SWIG doesn't understand
modern language features.
* Unlike SWIG, there is no risk that the wrapper code incorporates
incorrect type casts (this has happened on numerous occasions in
the past) since these will result in compile-time errors.
As a part of this change, the mechanism to define exported methods has
been redesigned slightly. New methods can be exported either by
declaring them in the SimObject declaration and decorating them with
the cxxMethod decorator or by adding an instance of
PyBindMethod/PyBindProperty to the cxx_exports class variable. The
decorator has the added benefit of making it possible to add a
docstring and naming the method's parameters.
The new wrappers have the following known issues:
* Global events can't be memory managed correctly. This was the
case in SWIG as well.

A previous change forced scons to spawn child processes by exec-ing it
directly rather than going through the shell because the command line
length would be too long for the shell to handle. Now that incremental
linking should keep the command line lengths more under control, that
change should no longer be necessary.

When a branch micro-op belongs to a flow and the micro-op does not change
the nPC and just updates the nuPC (like a 'rep movs' flow), branching()
function always returns not-taken no matter actual micro-branch outcome.
Provided fix adds to the equation nuPC attribute checking since these kind
of branch micro-op only updates that pointer.
This issue has been found while debugging the performance of a copy-loop
implemented with memcopy function. Without the fix, 'rep movss' internal
micro-branch was always predicted as not-taken causing an squash event
after every branch micro-branch execution.
Using the provided test, branch mispredition went from 1922 without the fix
to 7.

This patch fixes a bug where increasing the mmap region too much causes
it to run into already-allocated memory, which causes gem5 to fail an
assertion. Previously, the stack was incorrectly set up such that the
end of the mmap region and the top of the stack were the same address
and both would grow downward. With this patch, the top of the stack has
been separated from the end of mmap and moved up, and the mmap region
now grows upward instead of downward.

Previously, if a memory operation referenced an address that caused the
data to wrap around to the beginning of the memory (such as -1 or
0xFFFFFFFFFFFFFFFF), an assert would fail during address translation and
gem5 would crash. This patch fixes that by checking for such a case in
RISC-V's TLB code and returning a fault from translateData if that would
happen. Because RISC-V does support unaligned memory accesses, no
checking is performed to make sure that an access doesn't cross a cache
line.
