feature akin to the ARC runtime checks.  Removes a terrible hack where
IR gen needed to find the declarations of those symbols in the translation
unit.

test is still incomplete due to rewriter issues
unrelated to instancetype.

In some cases such as interpreters using indirectbr, the CFG can be very
complicated, and live range splitting may be forced to insert a large
number of phi-defs.  When that happens, traceSiblingValue can spend a
lot of time zipping around in the CFG looking for defs and reloads.

This patch causes more information to be cached in SibValues, and the
cached values are used to terminate searches early.  This speeds up
spilling by 20x in one interpreter test case.  For more typical code,
this is just a 10% speedup of spilling.

The previous version had bugs that caused miscompilations. They have
been fixed.

 --show-aliases (-a) shows aliases for commands, as well as built-in commands
 --hide-user-defined (-u) hides user defined commands
by default 'help' without arguments does not show aliases anymore. to see them, add --show-aliases
to have only built-in commands appear, use 'help --hide-user-defined' ; there is currently no way to hide
built-in commands from the help output
'help command' is not changed by this commit, and help is shown even if command is an alias and -a is not specified

what 'nullPos' is supposed to mean, at least at this one site.
Use closed forms for the arithmetic.  Rip out some clever but
ultimately pointless code that was trying to use 0 or 0L depending
the size of a pointer vs. the size of int;  first, it didn't work
on LLP64 systems, and second, the sentinel checking code requires
a pointer-typed value anyway, so this fixit would not have actually
removed the warning.
