grok_bin_oct_hex: Shortcut leading zeros
I noticed that leading zeros are quite common for octal and hex
constants. This code is structured for speed, with a partially unrolled
loop structured so that it is impossible to overflow the unrolled part.
If we get to the end of the unrolled portion, and the accumulated value
is still zero, it's because there have been only leading zeroes so far,
and instead of dropping into the loop, we can re-enter the unrolled part
without having to consider the possibility of overflowing. This allows
the next chunk of digits to be processed without branching.

grok_bin_oct_hex: Simplify flag
It's easier to understand and code if each flag name is for a single
flag.

grok_bin_oct_hex: fix broken return flags
Apparently no one has tried to use these before. These flags are to
suppress the display of certain warnings, but to instead return that the
suppression happened in output flags. The output flags were not getting
set.
I'm not adding a separate test, because a future commit will cause this
feature to be used regularly.

grok_bin_oct_hex: Improve overflow detection
The new scheme is is what toke.c already uses for the same purpose, and
I think is cleaner

grok_bin_oct_hex: Make a parameter const
This prevents a future maintainer from accidentally changing this
pointer inside the function, where its original value is needed at the
end
