[LLDB][MIPS] Provide CPU string to compiler for appropriate code generation for
MIPS
SUMMARY:
This patch implements ArchSpec::GetClangTargetCPU() that provides string
representing current architecture as a target CPU.
This string is then passed to tools like clang so that they generate
correct code for that target.
