[PATCH] D22590: Improve virtual register handling when computing debug information

OK I looked a little more wrt tests. The problem with MIR in this case is that `DbgValueHistoryCalculator` isn't a pass, it's just part of the AsmPrinter pass, which isn't really set up for MIR testing (e.g. for use with `llc -run-pass` etc). Maybe we should just add a regular wasm codegen test? It's not quite ideal since this is target-independent code, but it would cover this, and it could still be pretty simple.
