…ediate intrinsics

Those were removed from stdarch in rust-lang/stdarch#1463 (`simd_shl` and `simd_shr` are used instead)

Update stdarch submodule and remove special handling in cranelift codegen for some AVX and SSE2 LLVM intrinsics

rust-lang/stdarch#1463 reimplemented some x86 intrinsics to avoid using some x86-specific LLVM intrinsics:

* Store unaligned (`_mm*_storeu_*`) use `<*mut _>::write_unaligned` instead of `llvm.x86.*.storeu.*`.
* Shift by immediate (`_mm*_s{ll,rl,ra}i_epi*`) use `if` (srl, sll) or `min` (sra) to simulate the behaviour when the RHS is out of range. RHS is constant, so the `if`/`min` will be optimized away.

This PR updates the stdarch submodule to pull these changes and removes special handling for those LLVM intrinsics from cranelift codegen. I left gcc codegen untouched because there are some autogenerated lists.

Sync rustc_codegen_cranelift

Not much changed this time. Mostly doing this sync to make it easier to run the entire test suite on the in-tree version.

Use `Freeze` for `SourceFile`

This uses the `Freeze` type in `SourceFile` to let accessing `external_src` and `lines` be lock-free.

Behavior of `add_external_src` is changed to set `ExternalSourceKind::AbsentErr` on a hash mismatch which matches the documentation. `ExternalSourceKind::Unneeded` was removed as it's unused.

Based on rust-lang#115401.

Remove `verbose_generic_activity_with_arg`

This removes `verbose_generic_activity_with_arg` and changes users to `generic_activity_with_arg`. This keeps the output of `-Z time` readable while these repeated events are still available with the self profiling mechanism.

Sync rustc_codegen_cranelift

The highlights this time are improved simd and inline asm support, `is_x86_feature_detected!()` returning the actual cpu features when inline asm support is enabled and a couple of bug fixes.
