Subject: [PATCH] [clang] Expose -f(no-)strict-overflow as a clang-cl option
(#126512)
Also move the -fno-strict-overflow option definition next to the
-fstrict-overflow one while here.
Also add test coverage for f(no-)wrapv-pointer being a clang-cl option.
(cherry picked from commit 71adb054024a1e9bd5ed4566beda74dea65362cd)
