Changes in directory llvm/include/llvm/ADT:
Statistic.h updated: 1.20 -> 1.21
---
Log message:
Refactor statistic a big and introduce a horrible-but-necessary macro
(STATISTIC), which allows us to define statistics that don't introduce
static ctors into the .o files. I'm migrating code over to use this
incrementally.
