cdaee4aba7 pick off some easy cases for LUB/GLB in regions
the goal here is to minimize creating variables

ad6ca084e7 don't create region vars in LUB coercions

ee4b607dfb derive: assume enum repr defaults to isize
It was originally intended to be i32, but it isn't.

Fixes #31886.

2dbac1fb8e Add intrinsics for float arithmetic with fast flag enabled
`fast` a.k.a UnsafeAlgebra is the flag for enabling all "unsafe"
(according to llvm) float optimizations.

See LangRef for more information http://llvm.org/docs/LangRef.html#fast-math-flags

Providing these operations with less precise associativity rules (for
example) is useful to numerical applications.

For example, the summation loop:

    let sum = 0.;
    for element in data {
        sum += *element;
    }

Using the default floating point semantics, this loop expresses the
floats must be added in a sequence, one after another. This constraint
is usually completely unintended, and it means that no autovectorization
is possible.

24bb607e7d Auto merge of #32282 - sfackler:panic-hook, r=alexcrichton
Adjustments to the panic hook API

Rename `set_handler` and `take_handler` to `set_hook` and `take_hook` since we're not actually "handling" (i.e. fixing) anything.

Also alter `set_hook` to take a `Box<Fn(&PanicInfo) + 'static + Sync + Send>` rather than a parameterized closure since there's otherwise no easy way to re-register a hook that came from `take_hook`.

235d77457d Auto merge of #32080 - eddyb:transcendent, r=nikomatsakis
Refactor call & function handling in trans, enable MIR bootstrap.

Non-Rust and Rust ABIs were combined into a common codepath, which means:
* The ugly `__rust_abi` "clown shoes" shim for C->Rust FFI is gone, fixes #10116.
* Methods, *including virtual ones* support non-Rust ABIs, closes #30235.
* Non-Rust ABIs also pass fat pointers in two arguments; the result should be identical.
* Zero-sized types are never passed as arguments; again, behavior shouldn't change.

Additionally, MIR support for calling intrinsics (through old trans) was implemented.
Alongside assorted fixes, it enabled MIR to launch 🚀 and do a *complete* bootstrap.
To try it yourself, `./configure --enable-orbit` *or* `make RUSTFLAGS="-Z orbit"`.

74d00bde8e Make AssertRecoverSafe's field public
It's basically the very definition of a newtype, so we might as well
make things easy on people and let them construct and access it
directly.
