Merge mir query analysis invocations

The reasons I'm doing it is that

* merging those blocks allows for more parallelism as you don't run parallel blocks in sequence
* merging blocks allows merging analysis queries shrinking the dep graph
* should allow us to do more early aborting in case of errors and/or moving query calls from the analysis query into others that allow early aborting the others (and doing more tainting and stuff)
