Subject: [PATCH 1/5] [mlir][VectorOps] Support string literals in
`vector.print`
Printing strings within integration tests is currently quite annoyingly
verbose, and can't be tucked into shared helpers as the types depend on
the length of the string:
```
llvm.mlir.global internal constant @hello_world("Hello, World!\0")
func.func @entry() {
%0 = llvm.mlir.addressof @hello_world : !llvm.ptr<array<14 x i8>>
%1 = llvm.mlir.constant(0 : index) : i64
%2 = llvm.getelementptr %0[%1, %1]
: (!llvm.ptr<array<14 x i8>>, i64, i64) -> !llvm.ptr<i8>
llvm.call @printCString(%2) : (!llvm.ptr<i8>) -> ()
return
}
``
So this patch adds a simple extension to `vector.print` to simplify
this:
```
func.func @entry() {
// Print a vector of characters ;)
vector.print str "Hello, World!"
return
}
```
Most of the logic for this is now shared with `cf.assert` which already
does something similar.

I've also defined this in RunnerUtils so linking either or both gives

use cf.assert.
