9eca5e814d During vector shuffle lowering, we sometimes commute a vector shuffle to try 
to match MOVL (movss, movsd, etc.). Don't forget to commute it back and try
unpck* and shufp* if that doesn't pan out.

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.

b1c8802407 Fixed mingw\cygwin linkonce linkage once again. 
Added workaround for linker bug with linkonce sections.
Changed sections prefix to allow linker merge them
(PE loader doesn't like too much long-named sections :) )
All of this unbreaks libstdc++ on mingw32 allowing (small)
programs to be compiled, linked and run.

4fe4f254ce Fold "zero extending vector loads" now that evan added the chain manip stuff. 
This compiles both tests in X86/vec_ss_load_fold.ll into:

        subss LCPI1_0, %xmm0
        mulss LCPI1_1, %xmm0

        cvttss2si %xmm0, %eax
        andl $65535, %eax
        ret

instead of:

_test1:
        movss LCPI1_0, %xmm0
        movss 4(%esp), %xmm1
        subss %xmm0, %xmm1
        movss LCPI1_1, %xmm0

734503be59 X86ISD::CMP now produces a chain as well as a flag. Make that the chain 
operand of a conditional branch to allow load folding into CMP / TEST
instructions.

8cf723d8eb - Identify a vector_shuffle that can be turned into an undef, e.g. 
shuffle V1, <undef>, <undef, undef, 4, 5>
- Fix some suspicious logic into LowerVectorShuffle that cause less than
  optimal code by failing to identify MOVL (move to lowest element of a
  vector).

ffc0b2663e Eliminate X86ISD::TEST, using X86ISD::CMP instead. Match X86ISD::CMP patterns 
using test, which provides nice simplifications like:

-       movl %edi, %ecx
-       andl $2, %ecx
-       cmpl $0, %ecx
+       testl $2, %edi
        je LBB1_11      #cond_next90

There are a couple of dagiselemitter deficiencies that this exposes, they will
be handled later.

2926869b4a Fix a long-standing wart in the code generator: two-address instruction lowering 
actually *removes* one of the operands, instead of just assigning both operands
the same register.  This make reasoning about instructions unnecessarily complex,
because you need to know if you are before or after register allocation to match
up operand #'s with the target description file.

Changing this also gets rid of a bunch of hacky code in various places.

This patch also includes changes to fold loads into cmp/test instructions in
the X86 backend, along with a significant simplification to the X86 spill
folding code.
