debugger: Ensure space between opcode and operand.
...
Instructions that are 8 characters or longer (such as mtdbat3l) did not have a space between opcode and operand. Now there is always a space. The width of the opcode column is unchanged except for those opcodes that have 8 or more characters.

ppcexec: Rename bool function enums.
...
Use "logical" since the functions deal with multiple bits instead of a single boolean value and because the 601 manual calls them Logical Instructions.
Use "ppc" for the enums because logical_and is defined elsewhere and because the original DPPC code used these names for those functions.

debugger: Add list of input and output registers.
...
So the debugger can show them during stepping.
The fmt_* functions now take a PPCDisasmContext instead of just the ctx->instr_str so that they can alter the context.
Some fmt_* functions have an alternate (e.g. fmt_twoop_in for fmt_twoop) to indicate a difference in input/output registers.
The mtsrin and mfsrin instructions use a register to indicate which sr register to use.
The string instructions may affect multiple registers but only the first is included in the list.
Removed some extra blank lines.
Fixes:
lscbx: Add r0 check.
mftb: Do simplified if the spr is illegal. Maybe should do illegal opcode instead?
