eb0bc4759b Auto merge of #104054 - RalfJung:byte-provenance, r=oli-obk 
interpret: support for per-byte provenance

Also factors the provenance map into its own module.

The third commit does the same for the init mask. I can move it in a separate PR if you prefer.

Fixes https://github.com/rust-lang/miri/issues/2181

87237cb699 Add type_array to BaseTypeMethods 
Moved type_array function to rustc_codegen_ssa::BaseTypeMethods trait.
This allows using normal alloca function to create arrays as suggested in
https://github.com/rust-lang/rust/pull/104022.

5a1c8e8e5c Rewrite implementation of #[alloc_error_handler] 
The new implementation doesn't use weak lang items and instead changes
`#[alloc_error_handler]` to an attribute macro just like
`#[global_allocator]`.

The attribute will generate the `__rg_oom` function which is called by
the compiler-generated `__rust_alloc_error_handler`. If no `__rg_oom`
function is defined in any crate then the compiler shim will call
`__rdl_oom` in the alloc crate which will simply panic.

This also fixes link errors with `-C link-dead-code` with
`default_alloc_error_handler`: `__rg_oom` was previously defined in the
alloc crate and would attempt to reference the `oom` lang item, even if
it didn't exist. This worked as long as `__rg_oom` was excluded from
linking since it was not called.

This is a prerequisite for the stabilization of
`default_alloc_error_handler` (#102318).

simd: enable simd_as intrinsic 
The method context.convert_vector, added to libgccjit for simd_cast,
appears to give the correct behavior for simd_as.  Instead of
special-casing simd_as, re-use simd_cast's impl for simd_as.
