sse2 version of vp8_regular_quantize_b Added sse2 version of vp8_regular_quantize_b which improved encode performance(for the clip used) by ~10% for 32 bit builds and ~3% for 64 bit builds. Also updated SHADOW_ARGS_TO_STACK to allow for more than 9 arguments. Change-Id: I62f78eabc8040b39f3ffdf21be175811e96b39af

keep values in registers during quantization add an sse4 quantizer so we can use pinsrw/pextrw and keep values in xmm registers instead of proxying through the stack. and as long as we're bumping up, use some ssse3 instructions in the EOB detection (see ssse3 fast quantizer) pick up about a percent on 32bit and about two on 64bit.
