1. Simplify the implementation of AsmReadApplicationRegister() & AsmReadControlRegister() for IPF architecture.
2. Add AsmReadMsr() & AsmWriteMsr() for IPF architecture 3. update AsmCpuMisc.s to only support GCC tool chain to avoid symbol collision. git-svn-id: https://edk2.svn.sourceforge.net/svnroot/edk2/trunk/edk2@7034 6f19259b-4bc3-4df7-8a09-765794883524
