[nit][typo] Fix out of order words.
C `mem` function shims: consistently treat "invalid" pointers as UB Depends on rust-lang#113435.

It's similar to rust-lang/miri#3021 and should improve maintainability.

…Jung Replace hand-written binary search with Vec::binary_search_by. It's similar to rust-lang/miri#3021 and should improve maintainability.
When reporting a heap use-after-free, say where the allocation was allocated and deallocated This is a partial solution to: rust-lang/miri#2917 Currently in the interpreter, we only have accurate information for where heap allocations are allocated and deallocated (see rust-lang/miri#2940 (comment)). So this just implements support for allocations where the information is already available, and the full support will require more interpreter tweaks.
on out-of-bounds error, show where the allocation was created This seems useful, I think? r? `@saethlin`
If `size > 0` current implementation will first create an empty vec and then push an element into it, which will cause a resize that can be easily avoided. It's obviously not a big deal, but this also gets rid of `mut` local variable.
