emit_end_edge: squash C4244 MSVC warnings for 'nodeIntersect' calls

MSVC seems particularly pedantic about implicitly converting an unsigned 1-bit
bitfield to a bool:

  warning C4244: 'function': conversion from 'unsigned int' to 'bool'

These bitfields should really be signed (`int`) but it does not seem worth the
API break to do this.
