Valgrind trace for ticket #50 test conditions reports conditional move or jump in TEncSIFO.cpp

Memory allocation is excessive, possibly leading to crashes.

Memory usage has been analyzed for the following case: class B encoding with max CU=32x32, memory snapshot during encoding of 2nd frame

• Transform coefficients:

9 TComList objects 2040 CUs per frame 3 32x32 integer arrays per CU (luma+2*chroma), each array is 4KB 9 * 2040 * 3 * 32 * 32 * 4 = 215MB

• Luma frame buffers: 40 * 4.48MB = 179MB
• Chroma frame buffers: 79 * 1.12MB = 89MB
• Bitstream buffers (TComBitStream objects): 8 * 11.87MB = 95MB

For TE-9 S0-8, there several encoder crashes, one of them is attached as the bat\cfg and output txt for the crash analyse
