Remove unneeded intrinsics from Blackfin backend.
__builtin_bfin_ones does the same as ctpop, so it can be implemented in the front-end. __builtin_bfin_loadbytes loads from an unaligned pointer with the disalignexcpt instruction. It does the same as loading from a pointer with the low bits masked. It is better if the front-end creates a masked load. We can always instruction select the masked to disalignexcpt+load. We keep csync/ssync/idle. These intrinsics represent instructions that need workarounds for some silicon revisions. We may even want to convert inline assembler to intrinsics to enable the workarounds. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77917 91177308-0d34-0410-b5e6-96231b3b80d8
