Split to load_input_data4() and load_input_data8().
Use pack with signed saturation instruction for high bitdepth.

vpx_idct32x32_1024_add_ssse3() is actually a sse2 function and faster
than vpx_idct32x32_1024_add_sse2(). Replace the slow one. All are
code relocations, no new code.

It's almost identical with vpx_idct8x8_64_add_sse2(), except little
difference in instructions order.

- Refer to patch: 48fca113d inv_txfm_ssse3,butterfly: fix win32 abi
compatibility.
- Change four butterfly() calls to butterfly_self(), to simplify the
operations.

only the first 3 parameters can be aligned to 16 as required by __m128i,
make them all pointers for consistency.

- Split the inv txfm into three parts to avoid stack spillover.
- Function level speed improves ~12%.
- Use function and macro to remove some repeated code.

- Split the transform into first half and second half.
- Reschedule the instructions to avoid stack spillover.
- Function level speed improves ~16%.
Change-Id: I166889840d23aa8a273eca00f6fbdae8b4566f35
- Replace the corresponding assembly code.
- No user level speed performance degrade.
- Unit tests passed.
