When rejecting a march= or target-cpu command line parameter,
the message is quite lacking.  This patch adds a note that prints
all possible values for the current target, if the target supports it.

Additionally, this adds support for all TargetInfo types that reject
a setCPU call.  Note there is a corresponding LLVM patch for the ARM support.
