- In InterPrediction::rightShiftMSB, use existing floorLog2 function

- In addAvg_SSE, avoid unnecessary use of 32-bit path

- In copyBufferSimd, reduce number of loops

- In paddingSimd, take advantage of padding extent being either 1 or 2

- In addBIOAvg4_SSE, reduce number of operations and avoid nasty
Xmm register -> memory -> integer register path

Overall, a decoder runtime reduction of about 3% is expected

  - Add back support for reference wraparound with DMVR.

  - Prevent weighted prediction related processing when IBC or triangle prediction is enabled for the PU.

  - Reduce DMVR SAD cost by 2x to match spec.
  - Adjust BDOF-Disble and Zero-Cost thresholds accordingly.

2. add handling of JVET_O0108_DIS_DMVR_BDOF_CIIP when PROF is enabled

Adopt JVET-O0070 method 4-2.1a

JVET_O0594/O0252/O0506/O0615/O0624: BDOF reference sample padding using nearest integer sample positions

JVET-O0055 integer-distance DMVR cost to disable BDOF and disable BDOF early-termination in all cases

Cache is enabled incorrectly in DMVR processing

- add braces as suggested
- improve indentation of "else" branch
- fix consistently weird line breaks in clipMv function calls
