shared loop devices: This allows containers running the same image
to share a single loop device. This minimizes loop device usage and
helps optimize kernel cache usage.
Enabling this feature can be particularly useful for large MPI jobs.
The current `Spec.splice` model is very limited by the inability to splice specs that
contain multiple nodes with the same name. This is an artifact of the original
algorithm design predating the separate concretization of build dependencies,
which was the first feature to allow multiple specs in a DAG to share a name.
This PR provides a complete reimplementation of `Spec.splice` to avoid that
limitation. At the same time, the new algorithm ensures that build dependencies
for spliced specs are not changed, since the splice by definition cannot change
the build-time information of the spec. This is handled by splitting the dependency
edges and link/run edges into separate dependencies as needed.

macOS Sequoia's linker will complain if RPATHs on the CLI are specified more than once.
To avoid errors due to this, make `cc` only append unique RPATHs to the final args list.
This required a few improvements to the logic in `cc`:
1. List functions in `cc` didn't have any way to append unique elements to a list. Add a
`contains()` shell function that works like our other list functions. Use it to implement
an optional `"unique"` argument to `append()` and an `extend_unique()`. Use that to add
RPATHs to the `args_list`.
2. In the pure `ld` case, we weren't actually parsing `RPATH` arguments separately as we
do for `ccld`. Fix this by adding *another* nested case statement for raw `RPATH`
parsing. There are now 3 places where we deal with `-rpath` and friends, but I don't
see a great way to unify them, as `-Wl,`, `-Xlinker`, and raw `-rpath` arguments are
all ever so slightly different.
3. Fix ordering of assertions to make `pytest` diffs more intelligible. The meaning of
`+` and `-` in diffs changed in `pytest` 6.0 and the "preferred" order for assertions
became `assert actual == expected` instead of the other way around.

`cc` divides most paths up into system paths, spack managed paths, and other paths.
This gets really repetitive and makes the code hard to read. Simplify the script
by adding some functions to do most of the redundant work for us.

SimpleFilesystemView was producing an error due to looking for a
<prefix>/lib/.spack folder. Also, view_destination had no effect and
wasn't called. Changed this by instead patching in the correct
installation prefix for dictionaries.
Since aspell is using the resolved path of the executable prefix, the
runtime environment variable ASPELL_CONF is set to correct the prefix
when in a view. With this change aspell can now find installed
dictionaries. Verified with:
aspell dump config
aspell dump dicts
* shorten version number validations per reviewer feedback
* rename set_lib_path per reviewer feedback
* Add E4S tag
* Set CHPL_CUDA_PATH to ensure Chapel installer finds the right package
* Update ROCm dependency for Chapel 2.2
* Fix llvm-amdgpu and CHPL_TARGET_* for llvm=bundled
* Ensure CHPL_TARGET_COMPILER is set to "llvm" when required (llvm=spack
or +cuda or +rocm).
* Ensure CHPL_TARGET_{CC,CXX} are only set when using llvm=spack or llvm=none
* Use hip.prefix to set CHPL_ROCM_PATH
Since we might not directly depend on llvm-amdgpu, thus it might
not appear in our spec
* limit m4 dependency to +gmp
* limit names of env vars created from variants
* Ensure that +cuda and +rocm variants are Sticky
The concretizer should never be permitted to select GPU support, because
it's only meaningful and functional when the appropriate hardware is actually
available, and the concretizer cannot reliably determine that.
Also: Chapel's GPU support includes alot of complicated dependencies
and constraints, so leaving that choice free to the concretizer leads to alot
of extraneous and confusing messages when failing to concretize a
non-GPU-enabled spec.

Add pre-built sbcl for x86 and arm for various glibc versions, making
way for an actual sblc built from source.
Also switch to use set_env in a context manager over setting the
environment variable for the build environment. I hit an issue with the
build system due to this in the sbcl package, pre-empting the same issue
here.
