0949cd36c3 Auto merge of #1924 - RalfJung:ra, r=oli-obk 
hack to work around RA quirk

This is a gross hack to work around https://github.com/rust-analyzer/rust-analyzer/issues/10793: calling `cargo-miri/miri` does the same thing as calling `./miri`.

`@oli-obk` this is the best I could come up with... not sure if we want to have this in the repo. I am also okay with carrying `cargo-miri/miri` locally.

2cd6fe88d8 Auto merge of #1921 - RalfJung:overflow-checks-off, r=RalfJung 
test for overflow-checks=off

Strangely, if we call the functions in `std::ops`, we still get the panics. I assume that is because we build the stdlib with `-Cdebug-assertions=on`; probably the magic attribute that makes stdlib functions inherit overflow checks from the calling crate only works one way (namely to enable them when the calling crate asks for them, but not to disable them when the calling crate does not want them).

b258eb3c27 Auto merge of #1911 - RalfJung:rename-track-tag, r=RalfJung 
rename track-raw-pointers flag to tag-raw-pointers

The old flag name sounds too similar to `-Zmiri-track-pointer-tag`, which is a totally different kind of 'tracking'. This has lead to confusion in https://github.com/rust-lang/miri/issues/1907.

tweak cron job time

15:00 UTC is 16:00 in Europe and 10:00 on the US East Coast (during winter time, and 1h later during summer time), so a good time in both places to see the email and react quickly. No need to run this in the middle of the night if nobody will fix the problem anyway.

Move it 5min past the full hour to avoid what is probably a rush of cronjobs on the full hour.

This is important to be able to control which doctests run with `cargo miri test`. In particular, this is required for https://github.com/rust-lang/rust/pull/90909 to work as intended.

e6a9b2ce68 Update Miri for detecting uninitialized numbers 
This commit adds a `-Zmiri-check-number-initialization` flag to check
that integers and floats are initialized.

This commit also changes some shims to write at type `MaybeUninit<...>`
in order to prevent spurious errors from the uninit check.
