[mips] Add calling convention tests covering O32, N32, and N64.

Summary:
I had difficulty finding tests for the N32 and N64 ABI so I've added a
collection of calling convention tests based on the document MIPS ABIs
Described (MD00305), the MIPSpro N32 Handbook, and the SYSV ABI. Where the
documents/implementations disagree, I've used GCC to resolve the conflict.

A few interesting details:
* For N32, LLVM uses 64-bit pointers when saving $ra despite pointers being
  32-bit. I've yet to find a supporting statement in the ABI documentation but
  the current behaviour matches GCC.

* For O32, the non-variable portion of a varargs argument list is also subject
  to the rule that floating-point is passed via GPR's (on N32/N64 only the
  variable portion is subject to this rule). This agrees with GCC's behaviour
  and the SYSV ABI but contradicts part of the MIPSpro N32 Handbook which talks about O32's behaviour.

* The N32 implementation has the wrong callee-saved register list.
  (I already have a fix for this but will commit it as a follow-up).

I've left RUN-TODO lines in for O32 on MIPS64. I don't plan to support this case
for now but we should revisit it.

COFF: add support for .file symbols

Add support for emitting .file records.  This is mostly a quality of
implementation change (more complete support for COFF file emission) that was
noticed while working on COFF file emission for Windows on ARM.

A .file record is emitted as a symbol with storage class FILE (103) and the name
".file".  A series of auxiliary format 4 records follow which contain the file
name.  The filename is stored as an ANSI string and is padded with NULL if the
length is not a multiple of COFF::SymbolSize (18).

Andrea Di Biagio [Tue, 15 Apr 2014 19:30:48 +0000 (19:30 +0000)]
[X86] Improve the lowering of packed shifts by constant build_vector.

This patch teaches the backend how to efficiently lower logical and
arithmetic packed shifts on both SSE and AVX/AVX2 machines.

When possible, instead of scalarizing a vector shift, the backend should try
to expand the shift into a sequence of two packed shifts by immedate count
followed by a MOVSS/MOVSD.

Example
  (v4i32 (srl A, (build_vector < X, Y, Y, Y>)))

Can be rewritten as:
  (v4i32 (MOVSS (srl A, <Y,Y,Y,Y>), (srl A, <X,X,X,X>)))

[with X and Y ConstantInt]

The advantage is that the two new shifts from the example would be lowered into
X86ISD::VSRLI nodes. This is always cheaper than scalarizing the vector into
four scalar shifts plus four pairs of vector insert/extract.

[Allocator] Finally, finish nuking the redundant code that led me here
by removing the MallocSlabAllocator entirely and just using
MallocAllocator directly. This makes all off these allocators expose and
utilize the same core interface.

The only ugly part of this is that it exposes the fact that the JIT
allocator has no real handling of alignment, any more than the malloc
allocator does. =/ It would be nice to fix both of these to support
alignments, and then to leverage that in the BumpPtrAllocator to do less
over allocation in order to manually align pointers. But, that's another
patch for another day. This patch has no functional impact, it just
removes the somewhat meaningless wrapper around MallocAllocator.
