Move token_cache from cost_coeffs to MACROBLOCK This commit moves token_cache buffer into macroblock struct, instead of defining as a local variable in cost_coeffs. This avoids repeatedly re-allocating memory space in the rate-distortion optimization loop. The runtime at speed 0 reduces: bus 2000kbps, 161692ms to 159951ms football 600kbps, 229505ms to 225821ms Change-Id: If7da6b0b6d8c5138a16271a33c4548fba33d8840
