Top level function for rd-based intra mode selection during intra frame
encoding. This function will first search for the best luma prediction by
calling av1_rd_pick_intra_sby_mode, then it searches for chroma prediction
with av1_rd_pick_intra_sbuv_mode. If applicable, this function ends the
search with an evaluation for intrabc.
\param[in] cpi Top-level encoder structure.
\param[in] x Pointer to structure holding all the data for
the current macroblock.
\param[in] rd_cost Struct to keep track of the RD information.
\param[in] bsize Current block size.
\param[in] ctx Structure to hold snapshot of coding context
during the mode picking process.
\param[in] best_rd Best RD seen for this block so far.
\remark Nothing is returned. Instead, the MB_MODE_INFO struct inside x
is modified to store information about the best mode computed
in this function. The rd_cost struct is also updated with the RD stats
corresponding to the best mode found.

Computes SSE of a compound predictor constructed from 2 fundamental
predictors p0 and p1 using blending with mask.
r1: Residuals of p1.
(source - p1)
d: Difference of p1 and p0.
(p1 - p0)
m: The blending mask
N: Number of pixels
'r1', 'd', and 'm' are contiguous.
Computes:
Sum((MAX_MASK_VALUE*r1 + mask*d)**2), which is equivalent to:
Sum((mask*r0 + (MAX_MASK_VALUE-mask)*r1)**2),
where r0 is (source - p0), and r1 is (source - p1), which is in turn
is equivalent to:
Sum((source*MAX_MASK_VALUE - (mask*p0 + (MAX_MASK_VALUE-mask)*p1))**2),
which is the SSE of the residuals of the compound predictor scaled up by
MAX_MASK_VALUE**2.
Note that we clamp the partial term in the loop to 16 bits signed. This is
to facilitate equivalent SIMD implementation. It should have no effect if
residuals are within 16 - WEDGE_WEIGHT_BITS (=10) signed, which always
holds for 8 bit input, and on real input, it should hold practically always,
as residuals are expected to be small.
