Manman Ren	0ed04fc9ab	TBAA: handle scalar TBAA format and struct-path aware TBAA format. ... Remove the command line argument "struct-path-tbaa" since we should not depend on command line argument to decide which format the IR file is using. Instead, we check the first operand of the tbaa tag node, if it is a MDNode, we treat it as struct-path aware TBAA format, otherwise, we treat it as scalar TBAA format. When clang starts to use struct-path aware TBAA format no matter whether struct-path-tbaa is no, and we can auto-upgrade existing bc files, the support for scalar TBAA format can be dropped. Existing testing cases are updated to use the struct-path aware TBAA format. llvm-svn: 191538	2013-09-27 18:34:27 +00:00
