This adds a new scons flag --no-duplicate-sources to build without
linking source files to the build directory.
I find this very helpful when using CLion, since I can now generate a
compilation database using
`bear scons build/ALL/gem5.debug --no-duplicate-sources` and CLion will
now correctly semantically analyze all the files inside src/.
It also ensures that clicking on a build warning/error now opens the
real source file rather than a symlink.
This is not enabled by default since it's possible that certain use
cases are not working correctly, but the basic testing I've done so
far appears to work just fine.
It appears that with this change the `<root>/src` directory is no longer
added to `PYTHONPATH` when running `tests/main.py`, so this change
depends on https://gem5-review.git.corp.google.com/c/public/gem5/+/68757

The early call to child->step() was removed earlier because it confused the
new differences-only protocol ARM sendState() was using. It's necessary that
that gets called at least once before attempting to print the initial stack
frame, though, because otherwise statetrace doesn't know what the stack
pointer is. By putting the first call to child->step() in a common spot, both
needs are met.
Because of peculiarities in how system calls are returned from, single stepping executes some system calls and the instruction following them in a single step. Statetrace now patches the executable image when it detects a system call to force "correct" behavior, aka the appearance of stepping one instruction every single time.

The address of the stackpointer proceeding the vector minus 8 should be minus 16.

Fixed up to deal with microcode, and to make floating point register numbers correlate to the numbers used in SPARC.

util/statetrace/Makefile:
Makefile to build statetrace. Targets are:
statetrace: alias to build using the "native" compiler
statetrace-native: use the native compiler
statetrace-sparc: use the sparc cross compiler
I'll make this a little more fancy and capable later.

util/statetrace/printer.cc:
Implementation of the "Printer" objects which parse and output the state of the process after each instruction. There are currently two types of printers, nested ones and register ones. These are called NestingPrinter and RegPrinter respectively.

This is copied from m5. I should use the one already in the tree, but I'll do that later.

This file hooks in support for the appropriate architecture. Just the implementation is brought in, since the main program should ideally not have to know anything at all about an architecture other than it's interface.

An example output template for x86. A few example SPARC templates will be added later.
