Jim Ingham 5a98841673 Make raw & parsed commands subclasses of CommandObject rather than having the raw version implement an
Execute which was never going to get run and another ExecuteRawCommandString.  Took the knowledge of how
to prepare raw & parsed commands out of CommandInterpreter and put it in CommandObject where it belongs.

Also took all the cases where there were the subcommands of Multiword commands declared in the .h file for
the overall command and moved them into the .cpp file.

Made the CommandObject flags work for raw as well as parsed commands.

Made "expr" use the flags so that it requires you to be paused to run "expr".

Johnny Chen 2ffa754a6f After discussions with Jim and Greg, modify the 'watchpoint set' command to become a mutiword command
with subcommand 'expression' and 'variable'.  The first subcommand is for supplying an expression to
be evaluated into an address to watch for, while the second is for watching a variable.

'watchpoint set expression' is a raw command, which means that you need to use the "--" option terminator
to end the '-w' or '-x' option processing and to start typing your expression.

Also update several test cases to comply and add a couple of test cases into TestCompletion.py,
in particular, test that 'watchpoint set ex' completes to 'watchpoint set expression ' and that
'watchpoint set var' completes to 'watchpoint set variable '.

Johnny Chen 34ddc8db22 Refine the 'watchpoint set' command to now require either the '-v' option (for watching of a variable) or
the '-e' option (for watching of an address) to be present.

Update some existing test cases with the required option and add some more test cases.

Since the '-v' option takes <variable-name> and the '-e' option takes <expr> as the command arg,
the existing infrastructure for generating the option usage can produce confusing help message,
like:

  watchpoint set -e [-w <watch-type>] [-x <byte-size>] <variable-name | expr>
  watchpoint set -v [-w <watch-type>] [-x <byte-size>] <variable-name | expr>

The solution adopted is to provide an extra member field to the struct CommandArgumentData called
(uint32_t)arg_opt_set_association, whose purpose is to link this particular argument data with some
option set(s).  Also modify the signature of CommandObject::GetFormattedCommandArguments() to:

  GetFormattedCommandArguments (Stream &str, uint32_t opt_set_mask = LLDB_OPT_SET_ALL)

it now takes an additional opt_set_mask which can be used to generate a filtered formatted command
args for help message.

Options::GenerateOptionUsage() impl is modified to call the GetFormattedCommandArguments() appropriately.
So that the help message now looks like:

  watchpoint set -e [-w <watch-type>] [-x <byte-size>] <expr>
  watchpoint set -v [-w <watch-type>] [-x <byte-size>] <variable-name>

Johnny Chen dedb67ab9b Add "watch set" command as a more general interface in conjunction with "frame var -w".
Also add test cases for watching a variable as well as a location expressed as an expression.

o TestMyFirstWatchpoint.py:

  Modified to test "watchpoint set -w write global".

o TestWatchLocationWithWatchSet.py:

  Added to test "watchpoint set -w write -x 1 g_char_ptr + 7" where a contrived example program
  with several threads is supposed to only access the array index within the range [0..6], but
  there's some misbehaving thread writing past the range.

Johnny Chen 16dcf718d3 Add a commnad to set a condition for a watchpoint. Example:
watchpoint modify -c 'global==5'

modifies the last created watchpoint so that the condition expression
is evaluated at the stop point to decide whether we should proceed with
the stopping.

Also add SBWatchpont::SetCondition(const char *condition) to set condition
programmatically.

Test cases to come later.

Johnny Chen 6cc60e8668 Add capability to set ignore count for watchpoint on the command line:
watchpoint ignore -i <count> [<watchpt-id | watchpt-id-list>]

Add tests of watchpoint ignore_count for command line as well as API.
