[PATCH] D87865: PR47468: Fix findPHICopyInsertPoint, so that copies aren't incorrectly inserted after an INLINEASM_BR.

efriedma added inline comments.

================
Comment at: llvm/lib/CodeGen/PHIEliminationUtils.cpp:57
+    if ((EHPadSuccessor && I->isCall()) ||
+        I->getOpcode() == TargetOpcode::INLINEASM_BR) {
+      InsertPoint = I.getReverse();
----------------
Is it possible to have multiple INLINEASM_BR instructions in the same block?  If it is, we need to find the first one, not the last one.
