Rephrase error message to say "visible arguments" (#24318)
Vladislav Zavialov authored 
* Main change: make the error message generated by mkFunTysMsg more
  accurate by changing "value arguments" to "visible arguments".

* Refactor: define a new type synonym VisArity and use it instead of
  Arity in a few places.

It might be the case that there other places in the compiler that should
talk about visible arguments rather than value arguments, but I haven't
tried to find them all, focusing only on the error message reported in
the ticket.

GHC Testsuite Readme

For the full testsuite documentation, please see here.

Quick Guide

Commands to run testsuite:

  • Full testsuite: hadrian/build test
  • Using more threads: hadrian/build test -j12
  • Reduced (fast) testsuite: hadrian/build test --test-speed=fast
  • Run a specific test: hadrian/build test --only="tc055 tc054"
  • Test a specific 'way': hadrian/build test --test-way=optllvm
  • Skip performance tests: hadrian/build test --skip-perf
  • Set verbosity: hadrian/build test --test-verbose=<n> where n=0: No per-test output, n=1: Only failures, n=2: Progress output, n=3: Include commands called (default), n=4: Include perf test results unconditionally, n=5: Echo commands in subsidiary make invocations

Testsuite Ways

The testsuite can be run in a variety of 'ways'. This concept refers to different ways that GHC can compile the code. For example, using the native code generator (-fasm) is one way, while using the LLVM code generator (-fllvm) is another way.

The various ways that GHC supports are defined in config/ghc

Adding Tests
