Matt Pharr d74cc6397b Fix significant bug in mask management in code generated for 'foreach'.
In particular, we 1. weren't setting the function mask to 'all on', such that
any mixed function mask would in turn apply inside the foreach loop, and 2.
weren't always setting the internal mask to 'all on' before doing any additional
masking based on the iteration variables.
