[patch] Finishing touch for the std::error_code transition

[Rafael Espíndola]

Hi,

While std::error_code itself seems to work OK in all platforms, there
a few annoying differences with regards to the std::errc enumeration.

The attached patch adds a simple llvm enumeration, which will
hopefully avoid build breakages in other platforms and surprises as we
get more uses of std::error_code.

Cheers,
Rafael
