Added X86 StdCall & FastCall calling conventions. Codegen will follow.

DLL* linkages got full (I hope) codegeneration support in C & both x86
assembler backends.
External weak linkage added for future use, we don't provide any
codegeneration, etc. support for it.

We now compile CodeGen/X86/lea-2.ll into:

_test:
        movl 4(%esp), %eax
        movl 8(%esp), %ecx
        leal -5(%ecx,%eax,4), %eax
        ret

instead of:

_test:
        movl 4(%esp), %eax
        leal (,%eax,4), %eax
        addl 8(%esp), %eax
        addl $4294967291, %eax
        ret

  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).

3. Misc. kruft.

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.
