[PATCH] [C++] Save space in template_parm_index_s

[Andrew Pinski]

In template_parm_index_s, just like saved_scope, HOST_WIDE_INT is too 
big for the
index and the other fields as no one is going to have 2^15-1 template 
parameters or
levels, yes if this happens we can just change it back but it is not 
going to happen
with the limit of memory as it is now.

Ok? Bootstrapped on powerpc-apple-darwin7.2.0 with no regressions?

Thanks,
Andrew Pinski


ChangeLog:
	* cp-tree.h (template_parm_index_s) <index>: Change to a short.
	<level>: Likewise.
	<orig_level>: Likewise.
