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-passes` to the LTOCodeGenerator
- `--opt-remarks-passes` to lld
- `-pass-remarks-passes` to llc, opt, llvm-lto, llvm-lto2
- `-opt-remarks-passes` to gold-plugin

The naming is chosen to be consistent with the output filename.
