CodeView has its own register map which is defined in cvconst.h. Missing this mapping before saving register to CodeView causes debugger to show incorrect value for all register based variables, like variables in register and local variables addressed by register (stack pointer + offset). This change added mapping between LLVM register and CodeView register so the correct register number will be stored to CodeView/PDB, it aso fixed the mapping from CodeView register number to register name based on current CPUType but print PDB to yaml still assumes X86 CPU and needs to be fixed.
