1501cdbf63 Fix SmallVector's size calculation so that a size of 0 is 
handled correctly, and change a few SmallVector uses to use
size 0 to more clearly reflect their intent.

5f0cfa299d Rewrite ppc code generated for __sync_{bool|val}_compare_and_swap 
so that lwarx and stwcx are always executed the same number of times.
This is important for performance, I'm told.

22bb31103d Factor out the predicate check code from DAGISelEmitter.cpp 
and use it in FastISelEmitter.cpp, and make FastISel
subtarget aware. Among other things, this lets it work
properly on x86 targets that don't have SSE, where it
successfully selects x87 instructions.

1887c1c2f9 Fix a number of byval / memcpy / memset related codegen issues. 
1. x86-64 byval alignment should be max of 8 and alignment of type. Previously the code was not doing what the commit message was saying.
2. Do not use byte repeat move and store operations. These are slow.

0bfa1bfbff Move the handling of ANY_EXTEND, SIGN_EXTEND_INREG, and TRUNCATE 
out of X86ISelDAGToDAG.cpp C++ code and into tablegen code.
Among other things, using tablegen for these things makes them
friendlier to FastISel.

Tablegen can handle the case of i8 subregs on x86-32, but currently
the C++ code for that case uses MVT::Flag in a tricky way, and it
happens to schedule better in some cases. So for now, leave the
C++ code in place to handle the i8 case on x86-32.

242330371b Change WriteTypeSymbolic/WriteAsOperand to return void instead of 
an ostream, which is just weird.

Rename SC_DEBUG -> ST_DEBUG

Remove static indentation strangeness from WriteConstantInt.  This makes it 
so that large structs are not broken down and printed on multiple lines.  If
there is demand for this to return, there are better ways to implement this.
