[AArch64] Check fmul node single use in fused multiply patterns Check for single use of fmul node in fused multiply patterns to allow generation of fused multiply add/sub instructions. Otherwise fmul operation ends up being repeated more than once which does not help peformance on targets with only one MAC unit, as for example cortex-a53. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@197929 91177308-0d34-0410-b5e6-96231b3b80d8
