d5858d6dd2 Optimize static evaluation 
It greatly reduce the amount of constraints kept.

were kept when x and y were local params.

4d912e9349 Added more options for memalloc 
There is now three options for memory allocation:
  - -only-linear activates only the linear 
annotations (with typing and code generation)
  - -only-memalloc does only memory allocation
  - -memalloc does both

When linear typing is not activated, linearity 
annotations are ignored (the signature in the .epi
does not contain the annotations)

70787757aa Fixed normalization of fby 
The incorrect behaviour was introduced in commit
6b86b86e9d.

We should have:
       o = v fby e
     becomes
       mem_o = v fby e;
       o = mem_o

The old way would break with:
 v = true fby false fby v
that would generate unschedulable code.

linear types only), after the encoding of automata.
