[PATCH] Move logic from llvm::Triple::getARMCPUForArch to driver::tools::arm::getARMCPUForMArch

[Derek Schuff]

The out of line function is on the LLVM side, so that will be a separate commit (http://reviews.llvm.org/D8637)

I don't think that will work. This logic is supposed to override the StringSwitch; e.g. if the OS is FreeBSD and MArch is "armv6" then the CPU is supposed to be "arm1176jzf-s" but if this switch is moved, then the StringSwitch logic will return "arm1136jf-s"
