Add loop distribution to the LTO pipeline The LoopDistribute pass is missing from the LTO pipeline, so -enable-loop-distribute has no effect during post-link. The pre-link loop distribution doesn't seem to survive the LTO pipeline either. With this patch (and -flto -mllvm -enable-loop-distribute) we see a 43% uplift on SPEC 2006 hmmer for AArch64. The rest of SPECINT 2006 is unaffected. Differential Revision: https://reviews.llvm.org/D89896

Add !annotation metadata and remarks pass. This patch adds a new !annotation metadata kind which can be used to attach annotation strings to instructions. It also adds a new pass that emits summary remarks per function with the counts for each annotation kind. The intended uses cases for this new metadata is annotating 'interesting' instructions and the remarks should provide additional insight into transformations applied to a program. To motivate this, consider these specific questions we would like to get answered: * How many stores added for automatic variable initialization remain after optimizations? Where are they? * How many runtime checks inserted by a frontend could be eliminated? Where are the ones that did not get eliminated?
