71a1e57d18 Remember to free the heap allocated array if we're not going to use it.

b54b315251 Fix an issue where assignments that caused a SmallPtrSet to become non-small 
would result in calling realloc() on a null pointer.  Instead, if we encounter
this situation, make a normal call to malloc().

845b31de0c Unbreak the build by putting calls to free into the implementation file and 
having that implementation file #include <cstdlib>.

4d6f96d699 Make the assignment operator for SmallPtrSet return a reference, and fix a long-standing bug in the copy 
ctor while I'm at it.

Thanks to Chris Lattner for help with this patch.

61766cae0b Two changes: 
1. Make SmallPtrSet::erase faster in the small case by replacing a memmove
    with a pointer copy.
 2. Fix a bug where the null terminator at the end of the array in the small
    case was not copied

element was in the set.
