[PATCH] D114651: [clang-cl] Expose -Wall to clang-cl by unaliasing -Wall, keeping /Wall as alias to -Weverything

[Markus Böck via Phabricator via cfe-commits]

zero9178 added a comment.

Is the deviation from MSVC behaviour here intentional? MSVC flags allow both using a `/` as well as `-` as prefix. That means Both `-Wall` and `/Wall` are accepted by MSVC as well as clang-cl and in both compilers currently lead to ALL warnings being emitted. So this patch would deviate from that behaviour as well as add confusion as every other option behaves the same in MSVC and clang-cl, regardless of whether `-` or `/` is used as prefix.
