[PATCH] D30591: Introduce the feature "linux" for tests only for linux

[Taewook Oh via Phabricator via cfe-commits]

twoh created this revision.

This feature is needed to re-enable https://reviews.llvm.org/rL293004, which resembles gcc's behavior in
finding the input file name from a preprocessed source. The patch has been
reverted in https://reviews.llvm.org/rL293032, because the test checks FILE symbol of ELF file, which is
not valid on OSes not using ELF. With the patch, we can add "REQUIRES: linux"
to the tests on ELF files, or tests that require any linux-specific features.
