[C++] Add the "norecurse" attribute to main() if in C++ mode The C++ spec (3.6.1.3) says "The function `main` shall not be used within a program". This implies that it cannot recurse, so add the norecurse attribute to help the midend out a bit. llvm-svn: 252902

Slacken the norecurse test slightly It has been reported that this test currently fails on some Power buildbots due to them adding a "signext" function attribute. As that's not what we're checking here, slacken off the test a bit. llvm-svn: 253055
