A number of test cases assume that an "int" parameter or return value will be represented in the IR as a plain "i32" type. This causes the tests to spuriously fail on platforms where int is not a 32-bit type, or where the ABI requires attributes like "signext" or "zeroext" to be used. This patch adds -triple or -target parameters to force those tests to use the i386-unknown-unknown target. llvm-svn: 166551

'pure' and 'const' functions should also be marked nounwind. Migrate test over from llvm/test/FrontendC++ and update others to account for the change. llvm-svn: 137669
