Add a MCTargetStreamer interface. This patch fixes an old FIXME by creating a MCTargetStreamer interface and moving the target specific functions for ARM, Mips and PPC to it. The ARM streamer is still declared in a common place because it is used from lib/CodeGen/ARMException.cpp, but the Mips and PPC are completely hidden in the corresponding Target directories. I will send an email to llvmdev with instructions on how to use this. llvm-svn: 192181

This patch implements .set mips32r2 directive and sets appropriate feature bits. It also introduces helper functions that are used to set and clear feature bits as necessary. This directive is a counterpart of -mips32r2 command line options with the exception that it does not influence elf header flags. The usage example is gives in test file. llvm-svn: 202807
