Reid Spencer e0fc4dfc22 For PR950:
This patch implements the first increment for the Signless Types feature.
All changes pertain to removing the ConstantSInt and ConstantUInt classes
in favor of just using ConstantInt.

Chris Lattner 3323ce165d Teach scalarrepl to promote unions of vectors and floats, producing
insert/extractelement operations.  This implements
Transforms/ScalarRepl/vector_promote.ll

Chris Lattner fc34f8bb48 Fix a miscompilation of 188.ammp with the new CFE. 188.ammp is accessing
arrays out of range in a horrible way, but we shouldn't break it anyway.
Details in the comments.

Chris Lattner 8c9e14620f Fix Transforms/ScalarRepl/2005-12-14-UnionPromoteCrash.ll, a crash on undefined
behavior in 126.gcc on big-endian systems.

Chris Lattner 3b0a62d8a5 Implement a little hack for parity with GCC on crafty. This speeds up
186.crafty by about 16% (from 15.109s to 13.045s) on my system.

This turns allocas with unions/casts into scalars.  For example crafty has
something like this:

    union doub {
      unsigned short i[4];
      long long d;
    };
int f(long long a) {
  return ((union doub){.d=a}).i[1];
}

Instead of generating loads and stores to an alloca, we now promote the
whole thing to a scalar long value.

This implements: Transforms/ScalarRepl/AggregatePromote.ll

Nate Begeman 848622f87f Add support alignment of allocation instructions.
Add support for specifying alignment and size of setjmp jmpbufs.

No targets currently do anything with this information, nor is it presrved
in the bytecode representation.  That's coming up next.

Chris Lattner fe3f4e6ebd Teach SROA how to promote an array index that is variable, if the dimension
of the array is just two.  This occurs 8 times in gcc, 6 times in crafty, and
12 times in 099.go.

This implements ScalarRepl/sroa_two.ll
