Check for a mapping of an old language-name magicString to a LanguageID/CompilerSpec pair.
If returnLanguageReplacement is false, the returned LanguageID/CompilerSpec pair may no 
longer exist and may require use of an OldLanguage and translation process.
@param magicString old language name magic string
@param languageReplacementOK if true the LanguageID/CompilerSpec pair corresponding to the
latest language implementation will be returned if found, otherwise the a deprecated LanguageID/CompilerSpec pair
may be returned.  This parameter should be false if there is a sensitivity to the language implementation 
(e.g., instruction prototypes, etc.)
@return LanguageID/CompilerSpec pair or null if entry not found.
