Subject: [PATCH] * set all 16/32-bit specific stabs/dwarf register numbers of
 x86_64-only   registers to -1 in x86reg.dat. The values that used to be there
 weren't used   at all (most were just copies of the 32-bit version of the
 register). This can   be easily demonstrated by the fact that running 'make
 regdat' in the compiler   directory doesn't change any of the generated files
 for i8086/i386/x86_64.
