Subject: Port r198088 (set NO_DEAD_STRIP for clang) from make to cmake.
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=9b94cd4020939b7923013f41f90e53a4e355b219;p=clang

Port r198088 (set NO_DEAD_STRIP for clang) from make to cmake.

Also stop setting passing -dead_strip explicitly for libclang and instead
rely on this now happening by default. (And make it happen by default for
add_clang_library, which doesn't use the library cmake functions from llvm.)
