RFR: JDK-8240454: incorrect error message: as of release 13, 'record' is a restricted type name

[Vicente Romero]

Please review the fix for [1] at [2]. For this code:

class record {}

javac was issuing this error message:

class record {}
       ^
   as of release 13, 'record' is a restricted type name and cannot be 
used for type declarations

it should mention release 14 instead. This fix alters code that will 
affect similar error messages not only for uses of `record` but also of 
`yield`. In adding support for the test case I had modified several test 
libraries, in particular to be able to check not only the error key of 
the error issued by javac but also the parameters as in this case the 
difference was in the parameter passed to the error. Please review those 
changes too.

Thanks,
Vicente
