[PATCH] D158324: Revert "[RegisterCoalescing] Don't move COPY if it would interfere with another value"

[Bjorn Pettersson via Phabricator via llvm-commits]

bjope added inline comments.

Comment at: llvm/test/CodeGen/Mips/coalesce-partial-redundant-reguse-terminator.mir:27-29
+#  %1:gpr32 = COPY %0
 #
+# into bb.1 since %1 is used in the BEQ.
----------------
Something weird here. But since it talks about hoisting I figure this used to refer to the COPY in bb.2. So then it should be %3 instead of %1.
But then the "%3 is used in the BEQ" becomes weird. But now when it says %1 it is weird as well, because I don't see that %1 is used in any BEQ.
