The purpose of the auto-fallible job is to run builders that are likely
to fail on CI without gating on them. Having fast-fail enabled there
kinda defeats the purpose, as if one of them fails we can't monitor the
outcome of the other ones.

This was prompted by the aarch64-gnu builder consistently failing due to
a broken test, preventing us from seeing if the macOS spurious failure
is fixed.

riscv64 has an LLVM bug that makes rust-analyzer not build.

add `unsigned_abs` to signed integers

Mentioned on rust-lang/rfcs#2914

This PR simply adds an `unsigned_abs` to signed integers function which returns the correct absolute value as a unsigned integer.

ci: disable fast-fail on auto-fallible

Disable building rust-analyzer on riscv64

riscv64 has an LLVM bug that makes rust-analyzer not build. Should permit future rust-analyzer ups (e.g., rust-lang#74813) to land.
