Subject: uselistorder: Update for LLVM API change in r234959
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=18aa9e9198e979b6d2d9a6087188cdcdbd29aea3;p=clang

uselistorder: Update for LLVM API change in r234959

Now that `addBitcodeWriterPass()` requires an explicit bit to preserve
use-list order, send it in from `clang`.  It looks like I'll be able to
push this up to the `-cc1` options.
