Add new configure option, --disable-timestamps, intended to turn off anything which would mess up binary/object comparisons. Currently:
...
- Disables 'Built on ...' in 'foo --version'.
- Disables timestamps from being embedded into .dir files.

Refer to -help instead of --help since this is what tools themselves say.

Also, have tools output -help-hidden rather than refer to --help-hidden,
for consistency, and likewise adjust documentation. This doesn't change
every mention of --help, only those which seemed clearly safe.

Move the handling of CommaSeparated options into ProvideOption.
...
Makes '--comma-separated val1,val2' mean the same thing as
'--comma-separated=val1,val2' (that is, 'val1' and 'val2' are not lumped
together as 'val1,val2'). Also declutters the main loop a bit.

Several changes together in a murky mess:
...
1. Change some "\n" -> '\n'.
2. eliminte some std::string's by using raw_ostream::indent.
3. move a bunch of code out of the main arg parser routine into
a new static HandlePrefixedOrGroupedOption function.
4. Greatly simplify the implementation of getOptionPred, and make
it avoid splitting prefix options at = when that doesn't match
a non-prefix option.
