Clean up the 64-bitification of regs.dat for 64-bit ndisasm support

64-bit support required some major changes to regs.dat; clean some of
it up (re-introduce patterns, where appropriate) and allow a single
register to belong to multiple disassembly classes; also keep track
of the x86 register number again.

 # List of registers and their classes; classes are defined in nasm.h

-# The columns are: register name, assembler class, disassembler class, regval
-# A * means the line should be repeated for each value from 0 to 7
+# The columns are:
+#
+# register name, assembler class, disassembler class(es),
+# NASM register number, x86 register number
+#
+# If the register name ends in *, then it is repeated 8 times
+# with the following changes:
+# - a numerical tail to register number is incremented
+# - the NASM and x86 register numbers are incremented
+#
+# For 16-register register sets, two * lines are required.
