Sanjay Patel 97e4b98749 [ValueTracking] use nonnull argument attribute to eliminate null checks ... Enhancing value tracking's analysis of null-ness was suggested in D27855, so here's a first attempt at that. This is part of solving: https://llvm.org/bugs/show_bug.cgi?id=28430 Differential Revision: https://reviews.llvm.org/D28204 llvm-svn: 294897		2017-02-12 15:35:34 +00:00
