* upcxx: Update the UPC++ package to 2021.9.0
* Add the new release, and a missing older one.
* Remove the spack package cruft for supporting the obsolete build system that
was present in older versions that are no longer supported.
* General cleanups.
Support for library versions older than 2020.3.0 is officially retired,
for two reasons:
1. Releases prior to 2020.3.0 had a required dependency on Python 2,
which is [officially EOL](https://www.python.org/doc/sunset-python-2/)
as of Jan 1 2020, and is no longer considered secure.
2. (Most importantly) The UPC++ development team is unable/unwilling to
support releases more than two years old. UPC++ provides robust
backwards-compatibility to earlier releases of UPC++ v1.0, with very
rare well-documented/well-motivated exceptions. Users are strongly
encouraged to update to a current version of UPC++.
NOTE: Most of the lines changed in this commit are simply re-indentation,
and thus might be best reviewed in a diff that ignores whitespace.
* upcxx: Detect Cray XC more explicitly
This change is necessary to prevent false matches occuring on new Cray Shasta
systems, which do not use the aries network but were incorrectly being treated
as a Cray XC + aries platform.
UPC++ has not yet deployed official native support for Cray Shasta, but this
change is sufficient to allow building the portable backends there.
When running `spack install --log-format junit|cdash ...`, install
errors were ignored. This made spack continue building dependents of
failed install, ignoring `--fail-fast`, and exit 0 at the end.
Noting that missing numeric_limits was the cause of the compile issues
with gcc-11, I tested adding -include limits fixing @5.9:5.14%gcc@11.
Therefore, we can replace the conflicts('%gcc@11:', when='@5.9:5.14').

* Prevent additional properties to be in the answer set when reusing specs
fixes#27237
The mechanism to reuse concrete specs relies on imposing
the set of constraints stemming from the concrete spec
being reused.
We also need to prevent that other constraints get added
to this set.
See #25249 and https://github.com/spack/spack/pull/27159#issuecomment-958163679.
This adds `spack load --list` as an alias for `spack find --loaded`. The new command is
not as powerful as `spack find --loaded`, as you can't combine it with all the queries or
formats that `spack find` provides. However, it is more intuitively located in the command
structure in that it appears in the output of `spack load --help`.
The idea here is that people can use `spack load --list` for simple stuff but fall back to
`spack find --loaded` if they need more.
- add help to `spack load --list` that references `spack find`
- factor some parts of `spack find` out to be called from `spack load`
- add shell tests
- update docs

Reformulate variant rules so that we minimize both
1. The number of non-default values being used
2. The number of default values not-being used
This is crucial for MV variants where we may have
more than one default value
In our tests, we use concrete specs generated from mock packages,
which *only* occur as inputs to the solver. This fixes two problems:
1. We weren't previously adding facts to encode the necessary
`depends_on()` relationships, and specs were unsatisfiable on
reachability.
2. Our hash lookup for reconstructing the DAG does not
consider that a hash may have come from the inputs.
Concrete specs that are already installed or that come from a buildcache
may have compilers and variant settings that we do not recognize, but that
shouldn't prevent reuse (at least not until we have a more detailed compiler
model).
- [x] make sure compiler and variant consistency rules only apply to
built specs
- [x] don't validate concrete specs on input, either -- they're concrete
and we shouldn't apply today's rules to yesterday's build
In switching to hash facts for concrete specs, we lost the transitive facts
from dependencies. This was fine for solves, because they were implied by
the imposed constraints from every hash. However, for `spack diff`, we want
to see what the hashes mean, so we need another mode for `spec_clauses()` to
show that.
This adds a `expand_hashes` argument to `spec_clauses()` that allows us to
output *both* the hashes and their implications on dependencies. We use
this mode in `spack diff`.
- [x] Get rid of forgotten maximize directive.
- [x] Simplify variant handling
- [x] Fix bug in treatment of defaults on externals (don't count
non-default variants on externals against them)
