[llvm-dev] New llvm.commandline named metadata

[via llvm-dev]

Hi llvm-dev,

I have an implementation of -frecord-gcc-switches ready for Clang, and a 
named metadata node seemed like the correct way to approach this on the 
LLVM side. I have a review at https://reviews.llvm.org/D54487 which 
discusses some of the differences in implementation vs. GCC. A change to 
the set of "special" named metadata nodes seems like something that 
warrants an llvm-dev post, and I was not sure who specifically would be 
interested in reviewing the changes.

Thanks,
Scott
