Inconsistent use of allocator wrapper macros in libiberty

[Aaron W. LaFramboise]

Quite a few files in libiberty use XNEWVEC as a replacement for 
malloc(), but the they are being paired with plain free(); XDELVEC is 
not being used.


Is there some reason for the inconsistency, such as some transitional 
issue, or should this be fixed?

Not really.  Patches welcome.
