Subject: Revert "[Support] Allow the ability to change WithColor's auto detection function"
X-Git-Tag: upstream/15.0.7~15057
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3a167c4a90b0352ff3cca576392882e45b70dc36;p=platform%2Fupstream%2Fllvm.git

Revert "[Support] Allow the ability to change WithColor's auto detection function"

This reverts commit a83cf7a84628a9e3a24cfd33c69f786cf74df4ec because it
breaks a bunch of build bots.
