In preperation to move all remark utilities into one tool. We use command registry to breakdown each utility into a separate file. For now we have 3 utilities for remarks 1. Convert: which is responsible for converting yaml remarks to bitstream and vice-versa 2. Count: Analyse remarks and report count. This currently only supports asm-remarks and annotation-summary remarks. 3. Diff remarks: Currently we only have a diff for size remarks using `llvm-remark-size-diff` The first two utilites have been simplified and seperated into two files. The following commit will move `llvm-remark-size-diff` and fold it to be inside `llvm-remarkutil` as a subcommand Differential Revision: https://reviews.llvm.org/D156416
