[SE-0095] [Runtime], [Demangler], & AST printer updated to new composition syntax - All parts of the compiler now use ‘P1 & P2’ syntax - The demangler and AST printer wrap the composition in parens if it is in a metatype lookup - IRGen mangles compositions differently - “protocol<>” is now “swift.Any” - “protocol<_TP1P,_TP1Q>” is now “_TP1P&_TP1Q” - Tests cases are updated and added to test the new syntax and mangling
