When there are multiple filenames, print what got interpreted as filenames
I have written code that crafts command lines for rustc, and when I get "multiple input filenames provided" it can be quite hard to figure out where in this long list of arguments the mistake is hiding. Probably I passed an argument to a flag that does not expect an argument, but which flag would that be?
This changes the error message to print the first two filenames, to make it easier to debug what is going on.

Implement more detailed self profiling
Timing data and cache hits/misses are now recorded at the query level.
This allows us to show detailed per query information such as total time
for each query.
To see detailed query information in the summary pass the `-Z verbose`
flag. For example:
```
rustc -Z self-profile -Z verbose hello_world.rs
```
results in something like:
```md
Self profiling results:

Add a query type which is always marked as red if it runs
This is useful for queries which produce results which are very likely to change if their inputs do.
I also expect this to be useful for end to end queries because 1) we don't need `HashStable` impls and 2) we avoid the overhead of hashing the result of large results like the AST or the HIR map.

...
Make `intern_lazy_const` actually intern its argument.
Currently it just unconditionally allocates it in the arena.
For a "Clean Check" build of the the `packed-simd` benchmark, this
change reduces both the `max-rss` and `faults` counts by 59%; it
slightly (~3%) increases the instruction counts but the `wall-time` is
unchanged.
For the same builds of a few other benchmarks, `max-rss` and `faults`
drop by 1--5%, but instruction counts and `wall-time` changes are in the
noise.
