Raph Levien a0648a2153 Portability fixes
The MSL translation of the prefix example had its bindings permuted; a
flag prevents this (but, as is typical for shader translation,
potentially creates other problems).

Also use explicit unsigned literal to avoid DXC warnings.

Raph Levien 4ed339d434 Add tree reduction prefix sum test
Do a tree reduction in addition to the existing decoupled look-back, to
explore the tradeoff between performance and compatibility.
