Currently we have -Rpass for filtering the remarks that are displayed as diagnostics, but when using -fsave-optimization-record, there is no way to filter the remarks while generating them. This adds support for filtering remarks by passes using a regex. Ex: `clang -fsave-optimization-record -foptimization-record-passes=inline` will only emit the remarks coming from the pass `inline`. This adds: * `-fsave-optimization-record` to the driver * `-opt-record-passes` to cc1 * `-lto-pass-remarks-filter` to the LTOCodeGenerator * `--opt-remarks-passes` to lld * `-pass-remarks-filter` to llc, opt, llvm-lto, llvm-lto2 * `-opt-remarks-passes` to gold-plugin Differential Revision: https://reviews.llvm.org/D59268 Original llvm-svn: 355964 llvm-svn: 355984
