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.

a396e6d9ba Add some out-of-line virtual dtors so that the class has a "home", preventing 
vtables for (e.g.) Instruction from being emitted into every .o file.

2429ec5fdf Fix utostr once and for all, by making there only be one function named 
utostr.  To keep the efficiency in the 32-bit case, make it check to see if
the value is 32-bits and if so switch over to the faster 32-bit case.

574d4e6992 For PR786: 
Minor tweaks in public headers and a few .cpp files so that LLVM can build
successfully with -pedantic and projects using LLVM with -pedantic don't
get warnings from LLVM. There's still more -pedantic warnings to fix.

19068b431e Two fixes for the copy ctor/operator=: 
1. Make sure to clear() 'this' before adding elements to it
  2. Make sure that the leaders of the RHS EC are the leaders of the LHS EC.

b3103a3768 Rewrite this class, making the following improvements: 
1. It now actually uses tarjan's algorithm, so it is a efficient inverse
     ackerman's function for union operations, not linear time.
  2. It now stores one copy of the data in the set instead of two.
  3. It now works for elements other than pointers.
  4. It now has a more STL-like interface that exposes iterators instead
     of internal implementation details.
