bors de17464b14 Auto merge of #65881 - anp:implicit-caller-location, r=eddyb,oli-obk 
Implement #[track_caller] attribute. (RFC 2091 4/N)

Implements the `#[track_caller]` attribute in both const and codegen contexts.

The const implementation walks up the stack to find the nearest untracked callsite.

The codegen implementation adds an implicit argument to tracked function calls, and populates it with either a call to the previously-landed intrinsic or if the caller has `#[track_caller]` with a copy of the location passed to the current function.

Also includes a little cleanup and a few comments in the other caller location areas.

Simon Sapin cba479f75c Add `{f32,f64}::approx_unchecked_to<Int>` unsafe methods 
As discussed in https://github.com/rust-lang/rust/issues/10184

Currently, casting a floating point number to an integer with `as` is Undefined Behavior if the value is out of range. `-Z saturating-float-casts` fixes this soundness hole by making `as` “saturate” to the maximum or minimum value of the integer type (or zero for `NaN`), but has measurable negative performance impact in some benchmarks. There is some consensus in that thread for enabling saturation by default anyway, but provide an `unsafe fn` alternative for users who know through some other mean that their values are in range.

Nicholas Nethercote 02edd14cde Convert some `InternedString`s to `Symbols`. 
This avoids the needs for various conversions, and makes the code

Rollup merge of #62168 - ljedrz:the_culmination_of_hiridification, r=Zoxc 
The (almost) culmination of HirIdification

It's finally over.

This PR removes old `FIXME`s and renames some functions so that the `HirId` variant has the shorter name.
All that remains (and rightfully so) is stuff in `resolve`, `save_analysis` and (as far as I can tell) in a few places where we can't replace `NodeId` with `HirId`.

Nicholas Nethercote 257eaf523f Introduce `InternedString::intern`. 
`InternedString::intern(x)` is preferable to
`Symbol::intern(x).as_interned_str()`, because the former involves one
call to `with_interner` while the latter involves two.

The case within InternedString::decode() is particularly hot, and this
change reduces the number of `with_interner` calls by up to 13%.

r? @steveklabnik

Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!

Add intrinsic to create an integer bitmask from a vector mask

This PR adds a new simd intrinsic: `simd_bitmask(vector) -> unsigned integer` that creates an integer bitmask from a vector mask by extracting one bit of each vector lane.

This is required to implement: https://github.com/rust-lang-nursery/packed_simd/issues/166 .

EDIT: the reason we need an intrinsics for this is that we have to truncate the vector lanes to an `<i1 x N>` vector, and then bitcast that to an `iN` integer (while making sure that we only materialize `i8`, ... , `i64` - that is, no `i1`, `i2`, `i4`, types), and we can't do any of that in a Rust library.
