Summary:
Prior to Xcode 8 it was possible to search for build settings by their command-line argument equivalent (e.g. searching for "-Wdocumentation" filtered to the CLANG_WARN_DOCUMENTATION_COMMENTS build setting). Xcode 8 removed the command line arguments from build setting Quick Help, so this is no longer possible.

Steps to Reproduce:
1. Open project settings
2. Select the Build Settings tab
3. Select "All"
4. Enter "-Wdocumentation" in the build setting search field

Expected Results:
Build settings are filtered to include the "Documentation Comments" (CLANG_WARN_DOCUMENTATION_COMMENTS) build setting.

Observed Results:
All build settings are filtered out.

Version:
Xcode 8.3.2/8E2002

Notes:
This worked in Xcode 7.

This was a useful ability for several reasons:

- If after reviewing the build log you wanted to know what a particular compiler or linker option did, you could search for the equivalent build setting and view the Quick Help text right in the IDE.
- In the case of options added specifically for Apple LLVM, Xcode's Quick Help is sometimes the *only* source of documentation for the compiler flag.
- If you needed to disable a warning you could copy the compiler flag from the build log and then search for it to find the equivalent build setting.
- If you already knew a compiler flag you wanted to set you could search for it to find out if Xcode had an equivalent build setting.
