Subject: Some platforms use the same name for 32-bit and 64-bit registers
 (like %r3 on PPC) in their ASM files. However, it's hard for humans to read
 during debugging. Adding a new field to the register data that lets you
 specify a different name to be printed than the one that goes into the ASM
 file -- %x3 instead of %r3, for instance.
