Virgil Dupras 15628da7de lib/expr: make EXPR_PARSE put result in DE instead of IX 
Finally getting rid of this bad mistake of using IX for this.

Virgil Dupras cc754e12aa parseExpr --> parseExprDE: easy ones 
Those replacements were trivially equivalent. For the other ones, an
examination of the context is necessary.

Virgil Dupras 62eb5589c3 avra: refactor instruction tbl 
The instruction table is now beefier and has redundant data, but
this simplifies processing. This should simplify upcoming work.

Virgil Dupras ab578159b7 avra: refactor args parsing 
This costs us a bit of space for now but should make things a lot
simpler down the road, especially with "alias ops" which are simple
syntactic sugar for another op.
