Refactor MachRegs.trivColorable to do unboxed accumulation

trivColorable was soaking up total 31% time, 41% alloc when
compiling SHA1.lhs with -O2 -fregs-graph on x86.

Refactoring to use unboxed accumulators and walk directly
over the UniqFM holding the set of conflicts reduces this
to 17% time, 6% alloc.
