4cb4234c17 Take a baby step towards getting rid of inferred casts. Provide methods on 
CastInst and ConstantExpr that allow the signedness to be explicitly passed
in and reliance on signedness removed from getCastOpcode. These are
temporary measures useful during the conversion of inferred casts.

4e07e4aa24 Upgrade the ugly darwin 64-bit bswap idiom (bswap %eax / bswap %edx / 
xchgl %eax, %edx) to llvm.bswap.i64.  This compiles:

long long test2(long long A) {
  return _OSSwapInt64(A);
}

to:

_test2:
        movl 8(%esp), %eax
        movl 4(%esp), %edx
        bswapl %eax
        bswapl %edx
        ret

instead of:

_test2:
        movl 8(%esp), %edx
        movl 4(%esp), %eax
        bswap   %eax
        bswap   %edx
        xchgl   %eax, %edx
        ret

GCC manages (with -fomit-frame-pointer) the uglier:

_test2:
        subl    $4, %esp
        movl    8(%esp), %eax
        movl    12(%esp), %edx
        bswap   %eax

05a440d447 Implement signedness caching for values, value lists, constants and 
constant lists. This is just an internal change to the parser in
preparation for some backwards compatibility code that is to follow.
This will allow things like "uint 4000000000" to retain the unsignedness
of the integer constant as the value moves through the parser. In the
future, all integer types will be signless but parsing "uint" and friends
will be retained for backwards compatibility.

bddc114cfb Minor code layout tweak: if we have something like this: 
if (cond) goto BB2
BB1:
    ...
    return;
BB2:
   ...

Move BB1 to the end of the function so that the code falls through in the
non-return case.  This has the effect of moving assert (and other no-return
call) bodies and return blocks out of loops.

f50d87eb50 Rewrite the branch selector to be correct in the face of large functions. 
The algorithm it used before wasn't 100% correct, we now use an iterative
expansion model.  This fixes assembler errors when compiling 403.gcc with
tail merging enabled.

Change the way the branch selector works overall: Now, the isel generates
PPC::BCC instructions (as it used to) directly, and these BCC instructions
are emitted to the output or jitted directly if branches don't need
expansion.  Only if branches need expansion are instructions rewritten
and created.  This should make branch select faster, and eliminates the
Bxx instructions from the .td file.
