Currently, we only codegen the VRINT[APMXZR] and VCVT[BT] instructions when targeting ARMv8, but they are actually present on any target with FP-ARMv8. Note that FP-ARMv8 is called FPv5 when is is part of an M-profile core, but they have the same instructions so we model them both as FPARMv8 in the ARM backend. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@218763 91177308-0d34-0410-b5e6-96231b3b80d8
