ef3298e44e [docs] Add some information to DebuggingTheCompiler.md about working with the various simulators. 
I am adding this since I had to go spelunking around to find the SIMCTL_CHILD_
prefix which I need to debug an app. Rather than just forgetting it again, I
thought it made sense to just document it here so I can forget it again. I also
put in a little bit of other stuff about simctl as well while I was here.

82ac9328ae [NFC] CS: Misc minor debug output tweaks 
* Use fancy arrows (`→`) because they are distinct from and shorter than `->`,
  and fancier.
* We have two ways of demarcating locators: `@ <locator>` and `[[<locator>]];`.
  Stick to the first, which is shorter and clearer.
* 'attempting type variable' → 'attempting binding'. *Bindings* are attempted,
  not type variables.
* `considering ->` → `considering:`. I think a colon is semantically more fit
  and makes things easier to read if the considered constraint has arrows in its
  description or types. It’s also shorter this way.

8fe36eedd8 SILPassManager: improve bisecting for debugging the optimizer 
* Add the possibility to bisect the individual transforms of SILCombine and SimplifyCFG.
   To do so, the `-sil-opt-pass-count` option now accepts the format `<n>.<m>`, where `m` is the sub-pass number.
   The sub-pass number limits the number of individual transforms in SILCombine or SimplifyCFG.

* Add an option `-sil-print-last` to print the SIL of the currently optimized function before and after the last pass, which is specified with `-sil-opt-pass-count`.

d00a6cc0e3 [SIL][Frontend] Simplify debug info generation flow for SIL files 
- If any of the `-g<kind>` flag is given -- except `-gnone`, debug
   info will be printed into every generated SIL files.
 - The `-gsil` is deprecated in favor of `-sil-based-debuginfo`. The
   SILDebugInfoGenerator Pass now generates intermediate SIL file with
   name "<output file>.sil_dbg_<n>.sil". Other functionalities of that
   Pass remain the same.

ee5491a7c9 PassManager: simplify the options to print intermediate SIL. 
* rename -sil-print-only-function to -sil-print-function and -sil-print-only-functions to -sil-print-functions
* to print single functions, don't require -Xllvm -sil-print-all. It's now sufficient to use e.g. -Xllvm -sil-print-function=<f>
But it's still possible to select functions with -sil-print-function(s) for other print options, -sil-print-after.
