Instead of calculating this with mixed types promote all to the
larger type. This enables scalar evolution to analyze this

Revert r122955. It seems using movups to lower memcpy can cause massive regression (even on Nehalem) in edge cases. I also didn't see any real performance benefit.

instantiated function parameters, enabling instantiation of arbitrary
pack expansions involving function parameter packs. At this point, we
can now correctly compile a simple, variadic print() example:

  #include <iostream>
  #include <string>

  void print() {}

  template<typename Head, typename ...Tail>
  void print(const Head &head, const Tail &...tail) {
    std::cout << head;
    print(tail...);
  }

  int main() {
    std::string hello = "Hello";
    print(hello, ", world!", " ", 2011, '\n');

subclasses will automatically be able to take advantage of caching. The
cache line size is set to 512 by default.

This greatly speeds up stack backtraces on MacOSX when using the 
ProcessGDBRemote process plug-in since only about 6300 packets per second
can be sent.

Initial speedups show:

Prior to caching: 10,000 stack frames took 5.2 seconds
After caching: 10,000 stack frames in 240 ms!

About a 20x speedup!

Also fix an off-by-one in SelectionDAGBuilder that was preventing shuffle
vectors from being translated to EXTRACT_SUBVECTOR.
Patch by Tim Northover.

The test changes are needed to keep those spill-q tests from testing aligned
spills and restores.  If the only aligned stack objects are spill slots, we
no longer realign the stack frame.  Prior to this patch, an EXTRACT_SUBVECTOR
was legalized by loading from the stack, which created an aligned frame index.
Now, however, there is nothing except the spill slot in the stack frame, so
I added an aligned alloca.

We were never generating any of these nodes with variable indices, and there
was one legalizer function asserting on a non-constant index.  If we ever have
a need to support variable indices, we can add this back again.

In particular, the iteration variable (if present) should be created and
destroyed in a narrow span around the loop body, and the body should
be emitted in a cleanup scope in case it's not a compound statement.
Otherwise, rename a few variables and use phis instead of temporary
variables for the index and buffer count.
