[PPC] Remove isBarrier from CFENCE8's definition.
Summary:
This is my misunderstanding on isBarrier. It's not for memory barriers,
but for other control flow purposes. lwsync doesn't have it either.
This fixes a simple crash with -verify-machineinstrs like below:
define void @Foo() {
entry:
%tmp = load atomic i64, i64* undef acquire, align 8
unreachable
}
I deliberately don't want to check in the test, since there is little
chance to regress on such a mistake. Such a test adds noise to the code
base.
I plan to check in first, since it fixes a crash, and the fix is obvious.
