[llvm-commits] [PATCH] [ASan] fix lifetime intrinsics handling

[Alexey Samsonov]

Hi kcc,

Change the way we handle lifetime intrinsics: for each intrinsic check
if it describes one of the "interesting" allocas. Assume that allocas can go through
casts and phi-nodes before appearing as llvm.lifetime arguments.
