RFR: 8298943: Missing escapes for single quote marks in compiler.properties [v4]

[Archie L. Cobbs]

> The source file `compiler.properties` contains the English message bundle for compiler warnings, errors, etc.
> 
> Since the strings in this file are format strings, any single quotes must be escaped by doubling them.
> 
> An example of a properly encoded entry is:
> 
> 
> compiler.err.cant.assign.val.to.this=\
>     cannot assign to ''this''
> 
> 
> There are three entries that appear to be not escaped when they should be.
