Now that the profitable bits of EnableFullLoadPRE have been enabled by default, rip out the remainder.
Anyone interested in more general PRE would be better served by implementing it separately, to get real
anticipation calculation, etc.

Modify command options to use the new arguments mechanism.  Now all command option
arguments are specified in a standardized way, will have a standardized name, and
have functioning help.

The next step is to start writing useful help for all the argument types.

Add infrastructure for standardizing arguments for commands and
command options; makes it easier to ensure that the same type of
argument will have the same name everywhere, hooks up help for command
arguments, so that users can ask for help when they are confused about
what an argument should be; puts in the beginnings of the ability to
do tab-completion for certain types of arguments, allows automatic
syntax help generation for commands with arguments, and adds command
arguments into command options help correctly.

Currently only the breakpoint-id and breakpoint-id-range arguments, in
the breakpoint commands, have been hooked up to use the new mechanism.
The next steps will be to fix the command options arguments to use
this mechanism, and to fix the rest of the regular command arguments
to use this mechanism.  Most of the help text is currently missing or
dummy text; this will need to be filled in, and the existing argument
help text will need to be cleaned up a bit (it was thrown in quickly,
mostly for testing purposes).

Help command now works for all argument types, although the help may not
be very helpful yet.

Those commands that take "raw" command strings now indicate it in their
help text.

one results in an obscure error from the backend that doesn't make
sense.  Capture this information in the .def files for builtins with
a new "I" modifier letter indicating the an argument needs to be an ICE.

Nothing uses this yet, but sema will eventually enforce this (eliminating
some special cases from semachecking.cpp) and codegen will use this to 
force an ICE value, preventing backend error messages.
