Evgeniy Stepanov 7395cae005 [msan] Change the way origin ids are built. ... Previously, all origin ids were "chained" origins, i.e values of ChainedOriginDepot. This added a level of indirection for simple stack and heap allocation, which were represented as chains of length 1. This costs both RAM and CPU, but provides a joined 2**29 origin id space. It also made function (any instrumented function) entry non-async-signal-safe, but that does not really matter because memory stores in track-origins=2 mode are not async-signal-safe anyway. With this change, the type of the origin is encoded in origin id. See comment in msan_origin.h for more details. This reduces chained and stack origin id range to 2**28 each, but leaves extra 2**31 for heap origins. This change should not have any user-visible effects. llvm-svn: 223233		2014-12-03 13:58:40 +00:00
