d0337c1678 Remove assertions from the SmallVector class. They slow down clients of
smallvector too much in a release build.  Removing them speeds up isel 4%.

d91e5f911f The smallvector dtor should destroy the elements.
Implement pop_back.
Chage some code to use 'iterator' instead of T*.  This unbreaks operators=.

825405c0c1 Use std::copy instead of custom loops to take advantage of STL optimizations.
Add a new append method for appending a range.

f282654021 Add a new llvm::SmallVector template, which is similar to the vector class, but
contains optimizations to avoid heap allocation if the vector size is smaller
than some threshold.  This can significantly improve the performance of code
that allocates many small vectors by eliminating tons of small malloc/free's.
