Loading to single lanes in multiple registers is expensive since
it requires a read and write of each register which saturates
the register file access.  Loading to single registers followed
by a separate transpose reduces this pressure.

Removing assign_and_clamp_mv function, making implementation of clamp_mv
and clamp_mv2 more clear and consistent.

Adds a function to compute source variance for various
sb_types to be used for pruning mode and partition searches.
[The existing activity measure function is currently specialized
for only 16x16 MBs and needs to be updated].

The inverse 32x32 transform detects all zero entries and skips the
computations accordingly per 8 rows in the first 1-D operation. The
function vp9_short_idct10_32x32_add performs differently and is not
used anywhere, hence removed.

use_min_partition_size and use_max_partition_size are not used
currently, and could be added back if needed later.

This commit exploits the sparsity of quantized coefficient matrix.
It detects each 32x8 array and skip the corresponding inverse
transformation if all entries are zero.

For ped1080p at 8000 kbps, this on average reduces the runtime of
32x32 inverse 2D-DCT SSE2 function from 6256 cycles -> 5200
cycles. It makes the overall encoding process about 2% faster at
speed 0. The speed-up is more pronounceable for the decoding process.

This commit removes redundant arguments passing in the function of
rd_pick_reference_frame. This resolves the clang warnings about
potential use of uninitialized values.

Inlining VP9_NMV_UPDATE_PROB constant, consistent local variable names.

Change-Id: I01692501982568fa535882d6b320e3c692f88abb

Passing mi_row and mi_col parameters to functions explicitly. Removing
unused xd argument from scale_mv function.

Using different variable names "allow_hp" and "use_hp" instead of "usehp".

Refactor the frame buffer referencing in choose_partition and make
it consistent with other places. This means to prevent potential
issues when we extend reference frame buffer.

Change-Id: I5ff33ed5f671e1f4cc7049622212769a9b4578d9

Using inter-mode counts instead of inter-mode-tree branch counts inside
FRAME_COUNTS structure.

Removed unnecessary code lines, replaced switch with an if,
fixed spelling errors and formatting.
