LLDB supports many different register numbering schemes, and these are typically prefixed with an indicator that lets the user know what numbering scheme is used. The gcc numbering scheme is prefixed with gcc, and there are similar ones for dwarf, gdb, and gcc_dwarf. LLDB also contains its own internal numbering scheme, but the enum for LLDB's numbering scheme was prefixed differently. This patch changes the names of these enums to use the same naming scheme for the enum values as the rest of the register kinds by removing gpr_ and fpu_ prefixes, and instead using lldb_ prefixes for all enum values.
