0d3427b11d optimize 1.77MHz to 1MHz conversion 
fixed a few minor bugs here from qkumba's version as it was
making the validation tests fail.  One was not zeroing out
mixer/envelope, and one was not saving some values properly
in the 1MHz case --- vmw

dd18ecd1d9 cut some bytes and cycles 
- fire_r_same/up are now 10/12 instead of 8/15 cycles

some jmps can probably be replaced with appropriate branches instead

We do this by multiplying by 9/16 (which is a pain, but could be worse)
