Auto merge of #25570 - oli-obk:const_indexing, r=nikomatsakis
...
This PR allows the constant evaluation of index operations on constant arrays and repeat expressions. This allows index expressions to appear in the expression path of the length expression of a repeat expression or an array type.
An example is
```rust
const ARR: [usize; 5] = [1, 2, 3, 4, 5];
const ARR2: [usize; ARR[1]] = [42, 99];
```
In most other locations llvm's const evaluator figures it out already. This is not specific to index expressions and could be remedied in the future.

Move the core MIR datastructures to librustc.

This is done mostly so that we can refer to MIR types in csearch and other metadata related area.

represent fat ptr operands as 2 separate pointers

this does add some complexity, but to do otherwise would require unsized
lvalues to have their own allocas, which would be ugly.
