c68a1721c2 silence some "comparison between signed and unsigned integer expressions"

2340529c17 Fix some sporadic segfaults that are triggered when SmallVector's heap 
storage lands near the end of the available address space. In the expression
Begin+N > Capacity, the Begin+N was overflowing. Fix this by replacing it
by with an expression that doesn't involve computation of an address
beyond the end of allocated memory.

3490afcd50 fix a critical bug in smallvector, where it would destroy elements that are 
not in its range (!).

6c9bcb32a3 Split SmallVector into SmallVector and SmallVectorImpl, which allows us to 
eliminate code duplication due to the 'N' parameter.

3e1a9b0188 Remove assertions from the SmallVector class. They slow down clients of 
smallvector too much in a release build.  Removing them speeds up isel 4%.

b0bf058d33 The smallvector dtor should destroy the elements. 
Implement pop_back.
Chage some code to use 'iterator' instead of T*.  This unbreaks operators=.

d4d69f64dd 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.
