ensure current getrandom works with strict provenance

replace a borrow_mut by get_mut
This makes sure that cargo-miri works on all targets.
Track local frames incrementally during execution rust-lang/miri#2646 currently introduces a performance regression. This change removes that regression, and provides a minor perf improvement. The existing lazy strategy for tracking the span we want to display is as efficient as it is only because we often create a `CurrentSpan` then never call `.get()`. Most of the calls to the `before_memory_read` and `before_memory_write` hooks do not create any event that we store in `AllocHistory`. But data races are totally different, any memory read or write may race, so every call to those hooks needs to access to the current local span. So this changes to a strategy where we update some state in a `Thread` and `FrameExtra` incrementally, upon entering and existing each function call.

…that-cargo-miri-actually-works-kinda, r=RalfJung Test a small cargo-miri smoke test even in `run_tests_minimal` This makes sure that cargo-miri works on all targets. Implements the first step of rust-lang/miri#2685 (comment) to get that PR tested.
prettify our CI logs
make no_std work on Windows Also fixes rust-lang/miri#1123 by cherry-picking a patch by `@DrMeepster.`
also fix ICE on deallocation error and avoid redundant find_granting on retag
WASM uses the `.wasm` file extension for its binaries (just like how windows uses `.exe`), so we need to set that as well.
Rustup No changes happened on the rustc side, but I want to do a push next and would rather make josh's life easier by integrating some recent history first.
…notriddle Switch rustdoc-gui test to function call r? `@notriddle`
…llot Prefer doc comments over `//`-comments in compiler Doc comments are generally nicer: they show up in the documentation, they are shown in IDEs when you hover other mentions of items, etc. Thus it makes sense to use them instead of `//`-comments.
…ives, r=notriddle Remove Crate::primitives field It is a new approach to rust-lang#90447. Instead of removing primitives from everywhere (ie from `BadImplStripper`), I just removed them from the `Crate` type, allowing to reduce its size. cc `@camelid` r? `@notriddle`
update Miri r? `@ghost`
