Initial 64 bit direct object support.

This patch allows llvm to recognize that a 64 bit object file is being produced
and that the subsequently generated ELF header has the correct information.
The test case checks for both big and little endian flavors.

Correct error recovery when missing 'class' in a template template parameter.
...
The diagnostic message correctly informs the user that they have omitted the
'class' keyword, but neither suggests this insertion as a fixit, nor attempts
to recover as if they had provided the keyword.
This fixes the recovery, adds the fixit, and adds a separate diagnostic and
corresponding replacement fixit for cases where the user wrote 'struct' or
'typename' instead of 'class' (suggested by Richard Smith as a possible common
mistake).
I'm not sure the diagnostic message for either the original or new cases feel
very Clang-esque, so I'm open to suggestions there. The fixit hints make it
fairly easy to see what's required, though.

Hack the hack. If we have a situation where an ASM object is defined but isn't

I believe tuple is still under development in the standard. Daniel Krugler is/will be making convincing arguments that a modified form of LWG 2051 (currently NAD Future) is easily acheivable and desirable. He has demonstrated that a tuple<T...> where all of the T are implicitly convertible from U... should have a tuple constructor that is also implicit, instead of explicit. This would support the use cases in LWG 2051 while not undermining T... with explicit conversions from U.... This check-in is an experimental implementation of Daniel's work. I believe this work to be mature enough to warrant inclusion into libc++. If anyone sees real-world problems that this check in causes, please let me know and I will revert it, and provide the feedback to the LWG.

This commit contains a few changes that had to go in together.
...
1. Simplify xor/and/or (bitcast(A), bitcast(B)) -> bitcast(op (A,B))
(and also scalar_to_vector).
2. Xor/and/or are indifferent to the swizzle operation (shuffle of one src).
Simplify xor/and/or (shuff(A), shuff(B)) -> shuff(op (A, B))
3. Optimize swizzles of shuffles: shuff(shuff(x, y), undef) -> shuff(x, y).
4. Fix an X86ISelLowering optimization which was very bitcast-sensitive.
Code which was previously compiled to this:
movd (%rsi), %xmm0
movdqa .LCPI0_0(%rip), %xmm2
pshufb %xmm2, %xmm0
movd (%rdi), %xmm1
pshufb %xmm2, %xmm1
pxor %xmm0, %xmm1
pshufb .LCPI0_1(%rip), %xmm1
movd %xmm1, (%rdi)
ret
Now compiles to this:
movl (%rsi), %eax
xorl %eax, (%rdi)

Post-RA scheduling gives a significant performance improvement on

post-ra scheduling is all that we have for now, but that should have
more testing first).
