Code Review: Simple ruby fixes

tfpt review “/shelveset:rt;REDMOND\sborde”

Comment :
Simple fixes to the simple_test.rb runner as I was trying to get a
feel for all the moving parts in Ruby testing. “finished” was not
setting the exitcode, and so we were ignoring some failures, I disabled
some of the tests, and fixed the trivial ones.
Changed the Ruby method binder to throw AmbiguousMatchException for
ambiguous method overloads, as throwing the ArgumentException was
misleading.
Added an alias for building just Microsoft.Scripting.dll

Can you update Alias.ps1 as well? Otherwise looks good.

Looks good.
