tlst[inptype(...)] is bad C code because inptype() can realloc tlst
...
and there's no intermediate sequence point! We actually hit this on
sh3 with -O2 where gcc4 caches tlst in a register prior to recursive
call to inptype() and if you are unlucky the recursive call needs to
realloc tlst.
Introduce a temp variable to force a sequence point.

The symbol to define to 1 if a pointer to an int fits in a long is
...
INTPTR_IS_LONG, not INTPTR_IS_ULONG -- the latter is unused in
other parts of lint's code. This stops vax's lint from complaining
about conversion of integer constants to 'unsigned long' in function
argument lists, via a proper define of INT_RSIZE in common/inittyp.c.
sh3 defined this to 0, so was actually not affected, but better to
eradicate the typo there as well.

Remove the apparently always true "styp(nt) != SHORT" part of the

platforms.
