8b87dccf6e Indirect formatted scanning through the scanstate. 
This will allow us to reuse the scanning protocol with an arbitrary area
scanning function (replacing traceFormatScan) in order to implement
formatted object walking without an extra segment method.

Don't insist on scanning only grey segments: we want to be able to
reuse the scan protocol for walking, when the segments are black.

839ce9c6d3 Swap .gitignore and .p4ignore. 
Git version 2.32 added the backwards-incompatible "feature" that
.gitignore files that are symbolic links are ignored. Since all our
.gitignore files are symbolic links to the .p4ignore file in the same
directory, for compatibility between the Perforce and Git mirrors of
the repository, this broke "git status" for us and all our users.

See https://github.com/git/git/blob/master/Documentation/RelNotes/2.32.0.txt

This change swaps the files so that .p4ignore is a symbolic link to
.gitignore in each case.

68bf740f41 The mps no longer supports xci3ll (macos, i386, clang/llvm). 
As of macOS 10.15 (Catalina), this platform is no longer supported by
Apple, so it is inconvenient to develop and test. The code is left in
place for developers on older versions of macOS.

c133843a38 Exclude amcssth from test suites on arm64 for now. 
This is because amcssth fails often on arm64. We believe that this is
not a bug in the arm64 port (because the same failures are observed on
other architectures, but at a much lower frequency), but is rather
because amcssth's lockless multi-threaded updates lead to memory
ordering issues with arm64's relaxed memory ordering rules. We need to
identify all cases where out-of-order updates can happen, and add the
appropriate barriers to prevent them.

See GitHub issue https://github.com/Ravenbrook/mps/issues/59 for details.
