considered as available, which not true.

5c14a1bcb0 For PR950: 
Remove the getMaxValue and getMinValue functions from ConstantIntegral.
They don't make sense for a signless type. Also, for isMaxValue and
isMinValue, have the caller provided the signedness rather than obtaining
it from the constant's type.

5d52135a14 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

b78b908d4a 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.

45fb3f3cb2 For PR950: 
First in a series of patches to convert SetCondInst into ICmpInst and
FCmpInst using only two opcodes and having the instructions contain their
predicate value. Nothing uses these classes yet. More patches to follow.

36699cabc5 For PR950: 
Retain the signedness of the old integer types in a new TypeInfo structure
so that it can be used in the grammar to implement auto-upgrade of things
that depended on signedness of types. This doesn't implement any new
functionality in the AsmParser, its just plumbing for future changes.

4b10591265 Don't transform in another bad case: if the block is empty, it should be 
simplified before we do this xform so that our cost model is accurate.
