Fix codegen tests for RISC-V
Some codegen tests didn't seem relevant (e.g. unsupported annotations).
The RISC-V abi tests were broken by LLVM 10, c872dcf fixes that (cc: @msizanoen1)
I'm not sure about skipping catch-unwind.rs and included that change here mostly as a request for comment - I can't tell if that's a bug.
run-make regression test for issue #70924.
Sometime after my PR #72767 (to fix issue #70924) landed, I realized that I *could* make a local regression test, thanks to `rustc --print sysroot`: I can make a fresh "copy" (really mostly symlinks) of the sysroot, and then modify it to recreate the terms of this bug.
resolve: Sort E0408 errors by Symbol str
This is a request for comments implementing my suggested solution to https://github.com/rust-lang/rust/issues/72913
Previously errors were sorted by Symbol index instead of the string. The indexes are not the same between architectures because Symbols for architecture extensions (e.g. x86 AVX or RISC-V d) are interned before the source file is parsed. RISC-V's naming of extensions after single letters led to it having errors sorted differently for test cases using single letter variable names. Instead sort the errors by the Symbol string so that it is stable across architectures.
While I was at it, there's also 8edb05c2 skipping some ui tests which I think are irrelevant for risc-v.

LLVM 10 includes a009a60a917bc30940422bcef73f8270566d78db which will
print value numbers for unnamed func args.
Update these tests to be in line with the referenced clang tests.
Don't count pathless --extern for unused-crate-dependencies warnings
`--extern proc_macro` is used to add the proc_macro crate to the extern
prelude for all procmacros. In general pathless `--extern` only references
sysroot/standard libraries and so should be exempt from
unused-crate-dependencies warnings.

WF-check all ty::Const's, not just array lengths.
fixes#68977
This PR removes the special case for array length in `wf::compute` and
checks the well formedness of all consts.
Changes `PredicateKind::WellFormed` to take a `GenericArg` and updates `wf::obligations`.
Add a test to ensure Fuse stays covariant
When #70502 attempted to specialize the data types in `Fuse`, one of the problems we found was that it broke variance. This was also realized when `Fuse` was first added, https://github.com/rust-lang/rust/pull/35656#discussion-diff-74995079, but now this PR adds a test so we don't forget again.
Allow tests to use
// ignore-remote
to ignore the test when using remote-test-{client,server}. In most
situations this would be covered by
// ignore-cross-compile
but I see no reason that a non-cross compiled remote test runner
shouldn't work.
test miri-unleash TLS accesses
Finally gets rid of `IS_SUPPORTED_IN_MIRI`. :-)
I also added a test for the new `asm!` while I am at it.

Add descriptions for all queries
This also removes the default description for queries with DefId keys and makes the macro validate that a description is provided.

Avoid setting wrong obligation cause span of associated type mismatch
Removes code that sets wrong obligation cause span of associated type mismatch. See the linked issue for details.
Closes#72806.
