Incorporate name of parent func in name of "parallel for" task function.
Incorporate name of parent func in name of "parallel for" task function.

This gives us easier to decypher function names, a la
"par for FooBar.s0.y.yo", rather than just "par for s0.y.yo",
which made it hard to analyze profiling data from programs
with multiple Halide functions.
