[arm-fast-isel] Add support for fastcc.
Without fastcc support, the caller just falls through to CallingConv::C for fastcc, but callee still uses fastcc, this inconsistency of calling convention is a problem, and fastcc support can fix it. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@162013 91177308-0d34-0410-b5e6-96231b3b80d8
