965c87fb4a When disassembling, merge multiple PUSH ops 
Fonts typically have multiple consecutive PUSHB / PUSHW
operators.  Merge them in the disassembled output.

This, for now, generates worse assmebly because all PUSHB's
grouped with PUSHW's now generate as PUSHW.  Followup fix
will address that.

3714c78c92 When writing PUSH instructions, obey requested opcode 
Previously fonttools was choosing between the optimal opcode
from PUSHB, NPUSHB, PUSHW, and NPUSHW.  We now respect
whatever was requested and err if the format doesn't support
the data.

Morevoer, if the number of numbers to push is more than 255,
we add multiple push instructions to push all the numbers.

Finally, add a new pseudo-opcode "PUSH" that automatically
chooses the best format.

This, by itself, reduces roundtrip noise by not optimizing
the bytecode as it was before.  In a followup commit I'll
change the bytecode disassembler to always produce PUSH
in the textual instructions instead of the four variants.
That way, we get both the optimization during assembling,
and reduced noise in XML.

e93e29125f Don't write Format for Coverage, ClassDef, Single/Alternate/LigatureSubst 
The format values for those are automatically handled in
postRead/preWrite to choose optimal format.  As such, don't write them
in XML.  Reduces noise.

1a4f96b787 Remove total_ordering 
Upon studying further, we don't need it.  Since we only expect
comparing objects of the same type, just having __lt__ is enough.

assigning a new object to a function argument will not change the
original one, so we need to return the modified list.
