the target was branch fsharp4

Sigh!!!! .... it was missing the links.

fixes https://github.com/Microsoft/visualfsharp/issues/165

This is a pass of cleanup that renames some files to get rid of most cryptic abbreviations like "csolve", and does some other code cleanup and documentation too.

  - commenting in "detuple.fs"
  - removing ExtensibleDumper.fs which is an old adhoc debug mechanism barely used in the codebase
  - removing some dead code in fsc.fs (some code was already duplicated in fscmain.fs too!)
  - renaming check.{fs,fsi} --> PostInferenceChecks.{fs,fsi}
  - renaming tc.{fs,fsi} --> TypeChecker.{fs,fsi}
  - renaming opt.{fs,fsi} --> Optimizer.{fs,fsi}
  - renaming est.{fs,fsi} --> ExtensionTyping.{fs,fsi}
  - renaming build.{fs,fsi} --> CompileOps.{fs,fsi}
  - renaming fscopts.{fs,fsi} --> CompileOptions.{fs,fsi}
  - moving the option parser to CompileOptions.fs (where it belongs!)
  - marking some record types as RequireQualifiedAccess (to give better errors when editing the compiler)
  - removed a whole bunch of semicolons
  - removed some old debugging output (verboseStamps etc.)
