Stop using RBP as a base pointer, use offset from RSP instead. Initialize RSP on entry. Still need to start using RBP as an assignable register. Fixed the ELF examples, which had gotten broken at some point. Taught the disassembler to handle Group1 instructions. Updated disassembler test expected results to match using RSP instead of RBP for memory temps.
Made rbp available as an assignable register for Fog implicit temporaries. This breaks several tests due (at least) to bugs in AsmJit -- it can't handle BPL as a register.
Added two more ELF examples -- these as examples to see how GDB disassembles certain bytes.
Another example for GDB disassembly.
With the latest AsmJit (on the branch) all tests now pass. But why, with one more assignable register, does the tests that use up all of the assignable registers use the same number of stack temporaries? So maybe a bit more work to do.
