use VPX_NO_UNSIGNED_SHIFT_CHECK with entropy functions
these shift values off the most significant bit as part of the process;
vp8_regular_quantize_b_sse4_1 is included here for a special case of
mask creation
quiets warnings of the form:
vp8/decoder/dboolhuff.h:81:11: runtime error: left shift of
2373679303235599696 by 3 places cannot be represented in type
'VP8_BD_VALUE' (aka 'unsigned long')
vp8/encoder/bitstream.c:257:18: runtime error: left shift of 2147493041
by 1 places cannot be represented in type 'unsigned int'
vp8/encoder/x86/quantize_sse4.c:114:18: runtime error: left shift of
4294967294 by 1 places cannot be represented in type 'unsigned int'
vp9/encoder/vp9_pickmode.c:1632:41: runtime error: left shift of
4294967295 by 1 places cannot be represented in type 'unsigned int'
