5a1d7ab054 add a new pop_back_val method which returns the value popped. This is 
heretical from a STL standpoint, but is oh-so-useful for things that 
can't throw exceptions when copied, like, well, everything in LLVM.

440dea174f Implement a SmallVector insert method that can insert multiple 
copies of a value, and add several additional utilities to make
SmallVector better conform to the Container concept.

handled correctly, and change a few SmallVector uses to use
size 0 to more clearly reflect their intent.

27fa922841 Remove the SmallVector ctor that converts from a SmallVectorImpl. This 
conversion open the door for many nasty implicit conversion issues, and
can be easily solved by initializing with (V.begin(), V.end()) when 
needed.

This patch includes many small cleanups for sdisel also.

a03159bc35 generalize SmallVector copy ctor, there is no requirement for 
the initialization vector to have the same fixed size, just the
same element type.

0ca05878fe Iterators folloring a SmallVector erased element are invalidated so

8c5c7c8453 Change casts from old style to new style. This helps document the details 
better, gives the compiler a chance to validate the cast and reduces warnings
if the user turns on -Wold-style-cast option.

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.

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.
