Refactor duplicate functions

getARMCPU and getLLVMArchSuffixForARM existed as very similar functions
in both ToolChain.cpp and Tools.cpp. Create a single implementation of
each in Tools.cpp, eliminate the duplicate and share via Tools.h.

Creates an 'arm' namespace in Tools.h to be used by any ARM-targetting tools.
