Allow disasembler to work for any value of *print-base*.
With these changes, you can bind *print-base* to 16 and *print-case* to :downcase to get correctly printed disassembly in lower case with all numerical values in hex. If you want the radix marker as well, bind *print-radix* to T; the disassembly is still correct. src/compiler/disassem.lisp: o When printing out the source code, bind *print-base* to 10 so that the code is printed "naturally". src/compiler/x86/insts.lisp: o Use Carl's much cleaned-up print-mem-access o Update print-imm-data to use princ for all values, removing the special casing for NIL o When printing out xmm registers, honor *print-case*. src/general-info/release-20e.txt: o Update
