This patch fixes couple of bugs for predefined expression used inside blocks. It fixes a crash in naming code for __func__ etc. when used in a block declared globally. It also brings back old naming convention for predefined expression which was broken. rdar://18961148 llvm-svn: 222065

void syslog(const char *, ...);
void handler( );
Internal-linkage variables with constant-evaluatable initializers do not need to be emitted. (Also reduces the set of variables that need to be eagerly deserialized when using PCH / modules.) llvm-svn: 245497
